Description Zetok 2013-12-25 21:33:25 UTC

Application: systemsettings (4.11.4)
KDE Platform Version: 4.11.4
Qt Version: 4.8.5
Operating System: Linux 3.12.0-sabayon x86_64
Distribution: "Sabayon Linux amd64 14.01"

-- Information about the crash:
I opened systemsettings, gone into Workspaces behaviour, then Virtual desktops, and from there I tried to open Screen edges. That's when systemsettings crashed.

It was working before (in 4.10 IIRC), please repair it.

The crash can be reproduced every time.

-- Backtrace:
Application: Ustawienia systemowe (systemsettings), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".

Since there are created forks, there are few files, and their size is few megabytes, thus compressed archive.
I hope this helps. As long as I will be able to reproduce it, I can run some tests/whatever, as long as it will not make my system more unstable. Unfortunately, I think that quite soon I'll be using KDE 4.12, and because of it this may no longer be reproducible on my box. So if there are any questions, or commands need to run, better be fast.
