Package: claws-mail Version: 3.17.8-1+b1 Severity: normal A few emails I receive will cause claws-mail to hang in a CPU spin when attempting to preview it (by selecting it in the message list for preview in the third pane). This CPU spin consumes 100% of one core, with nothing visible to strace. The program does not respond to regular SIGINT/TERM and requires SIGKILL to quit it.
These cases are entirely repeatable, and all occur on github issue notifications from one particular author. Most notifications from that author do not hang, and work as expected. But occasionally one notification will cause a hang, and I have noticed the coincidence that it is always the same author. I shall attach a file directly from my Maildir containing such a case. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.9.0-2-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_WARN, TAINT_CRAP Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages claws-mail depends on: ii libc6 2.31-4 ii libcairo2 1.16.0-5 ii libcompfaceg1 1:1.5.2-5+b2 ii libenchant-2-2 2.2.15-1 ii libetpan20 1.9.4-3 ii libgdk-pixbuf2.0-0 2.40.0+dfsg-5 ii libglib2.0-0 2.66.7-2 ii libgnutls30 3.7.0-7 ii libgtk2.0-0 2.24.32-4 ii libice6 2:1.0.10-1 ii libldap-2.4-2 2.4.57+dfsg-2 ii libnettle8 3.7-2.1 ii libpango-1.0-0 1.46.2-3 ii libpangocairo-1.0-0 1.46.2-3 ii librsvg2-2 2.50.1+dfsg-1 ii libsm6 2:1.2.3-1 ii xdg-utils 1.1.3-4 Versions of packages claws-mail recommends: ii aspell-en [aspell-dictionary] 2018.04.16-0-1 ii claws-mail-i18n 3.17.8-1 ii xfonts-100dpi 1:1.0.4+nmu1.1 ii xfonts-75dpi 1:1.0.4+nmu1.1 Versions of packages claws-mail suggests: ii chromium [www-browser] 83.0.4103.116-3.1 pn claws-mail-doc <none> pn claws-mail-tools <none> ii elinks [www-browser] 0.13.2-1+b1 ii firefox [www-browser] 83.0-1 ii firefox-esr [www-browser] 78.3.0esr-2 ii google-chrome-stable [www-browser] 89.0.4389.90-1 ii lynx [www-browser] 2.9.0dev.6-2 ii mousepad 0.5.2-1 ii w3m [www-browser] 0.5.3+git20210102-6 -- no debconf information -- Paul "LeoNerd" Evans leon...@leonerd.org.uk | https://metacpan.org/author/PEVANS http://www.leonerd.org.uk/ | https://www.tindie.com/stores/leonerd/
