New crash information added by DrKonqi
konsole (2.12) on KDE Platform 4.12.0 using Qt 4.8.5
- What I was doing when the application crashed:
Earlier i noticed crashes in yakuake and did bug reports on #327105. After a while i've started yakuake with valgrind to see what's exactly happening inside and started konsole for things where i need a fast shell as yakuake is as slow as hell when executed with valgrind. A few minutes ago i closed a tab which i used some hours in konsole and it happened again as it did the last few times in yakuake.
- Unusual behavior I noticed:
No unusual behavior noticed. It just crashed without any warning.
- Custom settings of the application:
Infinite scroll buffer.

I think that #326805 and #323867 are definitely duplicates of this bug. This bug is reproducable by opening about 200-300 Tabs and closing them again until konsole crashes. As it happens several times a day for me, this is really an odd issue and therefor i would really appreciate if someone could actually provide a patch or at least take care of us. :) Created attachment 84388 [details]
valgrind log
I was able to reproduce the bug in a few seconds with strace `strace -fo /var/tmp/konsole.strace konsole` and then pressing ctrl-shift-t, waiting for the command line to appear, pressing ctrl-d and repeating the loop until it crashes. (I can reproduce the bug all the time if you want me to try out things). The output contains about 333k lines, so i've split it up into 10k lines files.

Currently, if I go over 100 tabs I start getting errors about too many open files open. Although konsole doesn't crash here. Reopen if you can still reproduce this issue with a recent konsole version. |
Application: konsole (2.11.2) KDE Platform Version: 4.11.2 Qt Version: 4.8.6 Operating System: Linux 3.10-3-amd64 x86_64 Distribution: Debian GNU/Linux testing (jessie) -- Information about the crash: - What I was doing when the application crashed: (This already happened in KDE 4.10.5.) Whenever I close a konsole tab, either in Konsole or Yakuake, there is a chance it (i.e. Konsole or Yakuake) will crash. I'm using ibus and have set the scrolling history ("Verlauf" in German) to infinite. I usually close tabs by pressing Ctrl-D. The crash happens less than half the time, but still often enough to cause a lot of annoyance. The crash can be reproduced sometimes. -- Backtrace: Application: Konsole (konsole), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
