Package: kmail Version: 4:17.08.3-2 Severity: normal --- Please enter the report below this line. --- kmail, kontact and other applications using Qt's WebEngine crash when using the nouveau Xorg driver and mesa 17.3.1.
The output is like this: nouveau: kernel rejected pushbuf: No such file or directory nouveau: ch25: krec 0 pushes 0 bufs 2 relocs 0 nouveau: ch25: buf 00000000 00000002 00000004 00000004 00000000 nouveau: ch25: buf 00000001 00000006 00000004 00000000 00000004 *** KMail got signal 11 (Exiting) Some search suggests that this is actually a well-known nouveau bug, which occurs with multithreaded rendering. Qt appears to have decided to disable GL with nouveau altogether for Qt 5.10: https://bugreports.qt.io/browse/QTBUG-41242 but for now, they suggest to set QT_XCB_FORCE_SOFTWARE_OPENGL=1 as a workaround. So until nouveau is fixed, or Qt 5.10 released and packaged, it may be sensible to - document this somewhere, e.g. with apt-listchanges or - try to detect the use of nouveau and automatically set the environment variable, or - use this ticket as documentation Also see - https://bugzilla.redhat.com/show_bug.cgi?id=1376107 - https://bugs.freedesktop.org/show_bug.cgi?id=91632 --- System information. --- Architecture: Kernel: Linux 4.14.0-2-amd64 Debian Release: buster/sid 500 unstable www.deb-multimedia.org 500 unstable ftp.de.debian.org --- Package information. --- Depends (Version) | Installed =================================================================-+- ================================== akonadi-server (>= 4:17.08~) | 4:17.08.3-2 kdepim-runtime (>= 4:17.08~) | 4:17.08.3-3 libkf5akonadisearch-bin (>= 4:17.08~) | 4:17.08.3-1 libkf5akonadisearch-plugins (>= 4:17.08~) | 4:17.08.3-1 libkf5grantleetheme-plugins (>= 17.08~) | 17.08.3-1 kio | 5.37.0-2 libc6 (>= 2.14) | libgcc1 (>= 1:3.0) | libgpgmepp6 (>= 1.10.0) | libkf5akonadiagentbase5 (>= 15.07.90) | libkf5akonadicontact5 | libkf5akonadicore5 (>= 4:17.08.0) | libkf5akonadimime5 | libkf5akonadisearchdebug5 | libkf5akonadisearchpim5 (>= 16.08.0) | libkf5akonadiwidgets5 (>= 4:17.08.0) | libkf5bookmarks5 (>= 4.96.0) | libkf5calendarcore5 (>= 15.07.90) | libkf5calendarutils5 | libkf5codecs5 (>= 5.4.0+git20141202.0008+15.04) | libkf5completion5 (>= 4.97.0) | libkf5configcore5 (>= 4.98.0) | libkf5configgui5 (>= 4.97.0) | libkf5configwidgets5 (>= 5.23.0) | libkf5contacts5 (>= 15.12.0) | libkf5coreaddons5 (>= 5.2.0) | libkf5crash5 (>= 5.15.0) | libkf5dbusaddons5 (>= 4.97.0) | libkf5followupreminder5 (>= 4:16.04.0) | libkf5gravatar5 (>= 4:15.12) | libkf5guiaddons5 (>= 4.96.0) | libkf5i18n5 (>= 4.97.0) | libkf5iconthemes5 (>= 5.0.0) | libkf5identitymanagement5 (>= 17.08.0) | libkf5itemmodels5 (>= 4.96.0) | libkf5itemviews5 (>= 4.96.0) | libkf5jobwidgets5 (>= 4.96.0) | libkf5kcmutils5 (>= 5.2.0+git20141003) | libkf5kiocore5 (>= 4.96.0) | libkf5kiofilewidgets5 (>= 4.96.0) | libkf5kiowidgets5 (>= 5.35.0) | libkf5kontactinterface5 | libkf5ksieveui5 | libkf5libkdepim-plugins | libkf5libkdepim5 (>= 16.04) | libkf5libkdepimakonadi5 | libkf5libkleo5 (>= 4:17.08.0) | libkf5mailcommon-plugins | libkf5mailcommon5 (>= 4:17.08.3) | libkf5mailtransport5 | libkf5mailtransportakonadi5 | libkf5messagecomposer5 | libkf5messagecore5 | libkf5messagelist5 | libkf5messageviewer5 | libkf5mime5 (>= 15.12.0) | libkf5mimetreeparser5 | libkf5notifications5 (>= 4.96.0) | libkf5notifyconfig5 (>= 4.96.0) | libkf5parts5 (>= 4.96.0) | libkf5pimcommon-plugins | libkf5pimcommon5 (>= 4:17.08.0) | libkf5pimcommonakonadi5 | libkf5pimtextedit5 (>= 17.08.0) | libkf5sendlater5 (>= 4:16.04.0) | libkf5service-bin | libkf5service5 (>= 4.96.0) | libkf5sonnetui5 (>= 4.96.0) | libkf5templateparser5 | libkf5textwidgets5 (>= 5.0.0) | libkf5tnef5 (>= 15.07.90) | libkf5wallet-bin | libkf5wallet5 (>= 4.96.0) | libkf5webengineviewer5 | libkf5widgetsaddons5 (>= 5.4.0+git20141119.0013+15.04) | libkf5windowsystem5 (>= 4.100.0) | libkf5xmlgui5 (>= 4.98.0) | libqgpgme7 (>= 1.10.0) | libqt5core5a (>= 5.9.0~beta) | libqt5dbus5 (>= 5.7.0~) | libqt5gui5 (>= 5.7.0) | libqt5network5 (>= 5.7.0~) | libqt5widgets5 (>= 5.7.0~) | libqt5xml5 (>= 5.7.0~) | libstdc++6 (>= 4.1.1) | Recommends (Version) | Installed ==================================-+-=========== accountwizard | 4:17.08.3-1 gnupg | 2.2.4-1 kdepim-addons | 17.08.3-1 kdepim-themeeditors | 4:17.08.3-1 mbox-importer | 4:17.08.3-1 pim-data-exporter | 4:17.08.3-1 pim-sieve-editor | 4:17.08.3-1 pinentry-qt | 1.0.0-3 OR pinentry-x11 | Suggests (Version) | Installed ==============================-+-============== clamav | kaddressbook | 4:17.08.3-1 kleopatra | 4:17.08.3-1 procmail | spamassassin | OR bogofilter | OR spambayes (>= 1.0.4-6) | OR bsfilter | OR crm114 | -- Carsten Pfeiffer
