Description Ole Jacob 2009-02-01 00:58:46 UTC 
Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    SuSE RPMs

Plasma main panel freeze randomly when computer is idle. Clicking clock for instance crashes the panel and it is restarted. This seems to start happening after being logged in for a couple of days, but after that happens daily. No desktop effects enabled, NVIDIA card with 180.22 driver. Plasma applets added to panel: digital clock, application launcher, device notifier, lock/logout, pager, quicklauncher, show widget dashboard, system monitor CPU, system monitor Network, system tray, task manager.
Comment 1 Dario Andres 2009-02-01 20:23:36 UTC 
May you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and try to post a complete backtrace here? Thanks :)
Comment 2 Ole Jacob 2009-02-02 17:58:40 UTC 
Hi,

Here is a backtrace. It says it is corrupt and probably useless, but looking at it it seems to contain the data needed.
-----
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.

Comment 3 Dario Andres 2009-02-02 21:45:19 UTC 
The backtrace doesn't contain a lot of information, but it seems that the crash is related to the Oxygen widget style code. 

Can you try switching to another widget style (SystemSettings->Appearances->Styles) to a non-Oxygen one (Plastique, CleanLooks) only for testing ?

Anyways we need to generate a better backtrace so you need to install the "libqt4" and "kdebase-runtime" debuginfo packages.

Thanks!
Comment 4 Ole Jacob 2009-02-02 22:26:37 UTC 
OK. I've done the change, and will report back. If there is no crash within a couple of days, I'll switch back to Oxygen and install the debuginfo packages.
Comment 5 Ole Jacob 2009-02-04 19:38:38 UTC 
I don't know if this is any more useful, but I've installed kdebase-runtime debuginfo package. There was no libqt4 debuginfo package fro suse 11.1. I was now using cleanlooks style.

Comment 6 Dario Andres 2009-02-04 20:04:15 UTC 
Mh, It's crashing in the same Qt painting functions:

#13 0x00007fb4bb086967 in QPainter::drawRects(QRectF const*, int) () from /usr/lib64/libQtGui.so.4 
#14 0x00007fb4bb088398 in QPainter::drawPixmap(QRectF const&, QPixmap const&, QRectF const&) () from /usr/lib64/libQtGui.so.4 

but from another place (Plasma paint svg instead of Oxygen draw code...), not sure if this different is because of the methods that Oxygen use to paint.

What Qt version are you using ?

Thanks
Comment 7 Ole Jacob 2009-02-09 22:01:37 UTC 
QT 4.4.3 from OpenSuse repo
Comment 8 Dario Andres 2009-02-09 22:07:17 UTC 
Can you install "libqt4-debuginfo" and paste a new (hopefully more complete) backtrace here? Thanks
Comment 9 Dario Andres 2009-03-25 19:14:04 UTC 
No response. Marking as NEEDSINFO
Comment 10 Ole Jacob 2009-04-26 16:47:56 UTC 
Is this of any more use? I have libqt4-debuginfo-4.4.3-4.7 installed.

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.

Comment 11 Aaron J. Seigo 2009-04-27 07:37:13 UTC 
the new backtrace isn't much help unfortunately :/

Ole, are you still using 4.2.0? if so, can you try updating to something newer like 4.2.2?
Comment 12 Ole Jacob 2009-04-28 08:16:45 UTC 
I've already upgraded to 4.2.2 from Suse. So what more can I do to get a proper backtrace? As far as I know I have all relevant debuginfo packages installed.
Comment 13 Dario Andres 2009-04-28 19:21:31 UTC 
Is your "libqt4-debuginfo" package the same version as "libtqt4" ?
"libqt4-debuginfo" should provide the debug symbols. May be there are another qt4-debug package in the repos. (I don't know)
Thanks
Comment 14 A. Spehr 2009-05-22 14:48:43 UTC 
What you are looking to fix in your backtrace is lines 5-12 under "thread 1". The part right after it says "KCrash". You don't want there to be ?? 

(Maybe 16-20 would be useful too)

It looks like you have some of the Qt debug stuff, but not all??? This is weird.
Comment 15 Aaron J. Seigo 2009-06-26 04:57:14 UTC 
there are some missing debug packages there still, but i recognize this crash. the key signature is drawPixmap -> drawRects -> into qt -> death.
