Comment 1 Frank Reininghaus 2014-02-12 07:46:31 UTC

Thanks for the bug report! Do you remember if you had "Show in Groups" enabled before the crash?

Comment 2 Daniel Faust 2014-02-12 08:25:57 UTC

Sure, I never use "Show in Groups", so no.

Comment 3 Frank Reininghaus 2014-02-12 09:49:36 UTC

Thanks for the quick response. Unfortunately, the backtrace doesn't tell much about the cause of the crash. There is nothing unusual in the crashing line. Maybe it's caused by memory corruption, which could come from anywhere.

So knowing about anything unusual that happened before the crash or any special setup might be helpful (maybe you had expanded folders in Details View?).

The most useful thing would be a Valgrind log (http://community.kde.org/Dolphin/FAQ/Crashes), but this is obviously hard to get if the crash is not reproducible and happens only rarely :-(

Comment 4 Daniel Faust 2014-02-12 10:04:05 UTC

I mostly use dolphin in icons view mode. No nepomuk. The folder that was opened when dolphin crashed contained only video files and a text file. Thumbnails are enabled for text and video files (using kffmpegthumbs).

I hoped that this crash report could be of use to you, but if it isn't, just discard it. Dolphin very rarely crashes and this will most probably not be reproducible.

Comment 5 Elvis Angelaccio 2016-12-10 11:51:19 UTC

Closing as requested. Please reopen if you can reproduce it with current Dolphin.

Comment 6 Julian Steinmann 2018-04-01 19:37:46 UTC

Actually closing now.
