Package: backintime-qt4 Version: 1.1.6-1 Severity: grave Justification: renders package unusable
Dear Maintainer, Trying to start the QT interface for backintime-qt4 using: $ gksu backintime-qt4 results in a blank grey window appearing, along with the output: Back In Time Version: 1.1.6 Back In Time comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to redistribute it under certain conditions; type `backintime-qt4 --license' for details.

This appears to be a common problem for some qt4 programs, and is fixed by running instead: $ gksu QT_X11_NO_MITSHM=1 backintime-qt4 in which case the program runs as normal. This problem has only recently started to affect my system, no idea why. Googling QT_X11_NO_MITSHM=1 shows that this affects a lot of QT apps that need gksu/gksudo. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.2.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages backintime-qt4 depends on: ii backintime-common 1.1.6-1 ii libnotify-bin 0.7.6-2 ii policykit-1 0.105-12 ii python3-dbus.mainloop.qt 4.11.4+dfsg-1+b2 ii python3-pyqt4 4.11.4+dfsg-1+b2 pn python3:any <none> ii x11-utils 7.7+3 Versions of packages backintime-qt4 recommends: ii python3-secretstorage 2.1.2-3 Versions of packages backintime-qt4 suggests: pn meld | kompare <none> -- no debconf information
