Description Hrvoje Senjan 2014-12-29 18:51:17 UTC 
Application: dolphin (4.60)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-rc1-1.g85f0072-desktop x86_64
Distribution: "openSUSE 20141225 (Tumbleweed) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

cleaned config for test user (~/.cache, ~/.config & ~/.local) to test plasma behaviour, and got dolphin crashed in such (missing) configuration..
after that, subsequent starts seem to haven't produced further crashes...

Qt is from 5.4 branch, KF5 master & kde-baseapps are HEAD of frameworks branch

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Frank Reininghaus 2014-12-30 00:02:57 UTC 
Thanks for reporting this issue. It has been reported already with a less detailed backtrace (bug 342012). It's most likely caused by https://git.reviewboard.kde.org/r/121480/, which replaces the deprecated natural sorting function from kdelibs4support by QCollator. It has turned out that the latter is, unlike the former, unfortunately not thread-safe.

possible fix for the crash v2

> patch does not fix crash..

Thanks for testing!

After digging into the QCollator source, the copy ctor only increases the ref count of the shared private collator instance, so we can't use the copy ctor of QCollator. Instead we must create a completely new collator object and use the setter methods to apply all the configuration.

Can you please test the attached patch again? Thanks!
