Bug#968756: inkscape: Inkscape crash on multiple undo-redo actions
Package: inkscape
Version: 1.0-1~bpo10+1
Severity: critical
Tags: upstream
Justification: breaks unrelated software
Dear Maintainer,
Inkscape crashes, recently causing Thunar to crash _too_.
The crash happens when many undo and redo actions are performed consecutively.
At first, I thought it was a one-time bug so I tried using the bpo. Once again, under the same conditions, Inkscape crashed. Finally, I tried using the 1.0 AppImage (to test "sterile" and see if this was Debian-specific or Inkscape in general). The result is the same. Since it wasn't a "world-ender" bug, I went back to using the native Debian bpo and decided to just save a lot (side-note: auto-save and recovery still occasionally fails).
Earlier tonight, something serious happened; it crashed all instances of Thunar. Clearly this bug seems to be worse than I thought -- apologies for not reporting it sooner. Sadly, this bug is not absolutely reproducible. It has only happened a few times, always under the same conditions though.
It may be related to other similar bugs involving memory access errors. I have noticed only complex SVGs do this (memory/cache?).
The errors (see below) point to the problem being Inkscape-specific (the core lib), so it's very concerning that there's this "domino effect".
Here's the relevant dmesg outputs:
inkscape[18142]: segfault at 148 ip 00007efbfefec5db sp 00007ffbffff9620 error 4 in libinkscape_base.so[7efbfe58a000+bb0000]
traps: inkscape[28062] general protection fault ip:7efbfeed39a1 sp:7ffbffff8520 error:0 in libinkscape_base.so[7efbfe58a000+bb0000]
If I have time, I'll try running Inkscape and Thunar from two consoles and try to reproduce the error. Hopefully it'll shed some light on it. Hopefully still, I won't need to.
Regards,
Jason
