Description m.wege 2010-02-19 17:12:09 UTC 
Version:           unknown (using 4.4.00 (KDE 4.4.0), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.31-20-generic

several kde-apps are spamming the xsession-errors, so that it reaches a size of many hundert megabytes. i do not think this is good idea putting debug messages of such a size in a release version of kde. especially since this output does not seem to contain errors.

following apps are doing this
- kio-imap4
- kio-htpp
- kopete skype
- kopete yahoo
- plasma-desktop
Comment 1 Dario Andres 2010-02-20 00:40:00 UTC 
- If you run "kdebugdialog", are all the entries disabled ? If some of them are enabled, could you try disabling them all and checking if that "fixes" the issue ?
Regards
Comment 2 m.wege 2010-02-20 21:35:31 UTC 
thanks, that fixed it mostly. now i only have ksystemlog which is running as root with many messages and knotify with a few messages.
Comment 3 Dario Andres 2010-02-20 21:44:46 UTC 
- Did you manually enabled those entries ?
THey should be disabled by default IMHO (I don't really know if that is true)
Regards
Comment 4 Tristan Miller 2010-03-28 16:14:51 UTC 
This appears to be a duplicate of Bug 174365.
Comment 5 Tristan Miller 2010-04-12 10:43:45 UTC 
I can confirm as well that disabling everything in kdebugdialog mostly fixes the issue.  Can a developer please confirm that the checkboxes are unchecked by default in new installations?  Leaving them checked by default can easily lead to users running out of disk space.
Comment 6 Tristan Miller 2010-04-12 11:04:07 UTC 
I've raised a separate report for KNotify: Bug 234140
Comment 7 Nick 2010-06-11 19:12:04 UTC 
I can refute that disabling everything in kdebugdialog mostly fixes it.
I've been logged in for only 2 days now, and I've got a 140MB .xsession-errors file.


.xsession-errors size: 141678730
Note, the firefox errors below account for 1.6MB -- less then 1%. It's all KDE.

The QPainter messages account for 136MB of it.
The kdeinit4 messages account for less than 1MB.
The konqueror messages account for over 2MB.

So, it looks like QPainter is the biggest culprit--so actually it's QT--but maybe due to the way KDE is using it somewhere.

Can we please get this fixed? I shouldn't have to symlink .xsession-errors to /dev/null just to keep my desktop responsive.

Comment 8 Christoph Feck 2010-06-17 15:56:32 UTC 
Since QPainter::hasClipping is only used by khtml/rendering, I assume the QPainter messages are caused by HTML widgets.

Comment 11 Nick 2010-10-16 16:57:15 UTC 
Any chance this will apply against 4.4.5?

I just had my system fail due to a 140GB .xsession-errors file...

The other bug related to this, is the fact that during the kde login, .xsession-errors is forcefully replaced with a regular file. (A symlink to /dev/null is replaced.)
Comment 12 Tommi Tervo 2010-10-16 17:13:22 UTC 
Comment #11:
I've not checked but that patch should apply to 4_4/5-branch cleanly.
