Bug 340738

Thanks for the bug report!

Interesting - I don't think that a crash like this has been reported before. I think that we need more information in order to understand the cause of the problem. Please install packages with debugging information that your distro provides for Dolphin. If possible, it would also help if you could provide a Valgrind log. Please see

https://community.kde.org/Dolphin/FAQ/Crashes

for details. Thanks for your help!

Thanks, but it seems that some debugging info is still missing (some line numbers in the interesting parts of the backtrace are still missing). Moreover, the Valgrind log doesn't show anything unusual - was the log taken when Dolphin was running normally, without crash? If possible, please create a new Valgrind log of a crashing Dolphin session. Thanks!

Sorry but when I start dolphin with valgrind it not segfault and now when it start without valgrind it shows Signal: Aborted instead of Segfault.
When I start as root it not segfault nor aborted. It is an headache situation.

Given that this was a report from Gentoo, I assume this is long fixed.
