[SOLVED] Plasma workspace crash (SIGSEGV) at login after update

Question

Hi all,
after I updated via pacman -Syu last weekend and rebooted my system I got a plasma workspace crash at the login which happens ever since.
I get:
The application Plasma Workspace (plasma) crashed and caused the signal 11 (SIGSEGV).
Please help us improve the software you use by filing a report at http://bugs.kde.org. Useful details include how to reproduce the error, documents that were loaded, etc.
and the following bug report:
This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

[2009-05-24 09:55] upgraded qtmod (4.5.1-2 -> 4.5.1-3)
However I've downgraded all of them back but the crash remains. I also removed qtmod and installed qt from the arch repositories but still no effect on the bug. Also tried to rename the .kde4/ folder to make KDE generating a new plain folder but doesn't help with the problem. Even complete removal of KDEmod and new installation didn't make a change.
I hope someone can help cause I'm runnig out of ideas what to try next.
thanks, potzi

Answer 1

You can find old packages here:
http://arm.kh.nu/
That repo has saved my life a number of times. Especially with BLUETOOTH GRRRR.
As for getting all your old settings back, I didn't investigate this enough because i only have opensuse for curiosity as I think they do some really great stuff.
Basically I hadn't yet isolated what was causing the problems before I gave up because every time I tried to merge my old settings in to the new user account, I recreated the problem. No logical (subjective term obviously) separation of what to merge and what not to merge worked. So I gave up and just did everything manually. Sorry that I couldn't be more helpful.
