Description jerome 2007-12-14 10:23:39 UTC

Version:           4.97 (using KDE KDE 3.97.0)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc 4.2/4.1(not sure) 
OS:                Linux

Oups, I've posted in a solved bug before ^^

knotify bug on startup, which open a new knotify window, and a new window....etc a big loop ^^

So I'm unable to kill knotify(about 56 windows opened :( ).
I will try to send you some log, but tell me wich log you want to debug knotify crash.

I'm using debian experimental packages on debian official repository to test KDE4, and I've made apt-get remove --purge ... to make a clean install of the RC2.

I'm using ~/.kde4/share/config/startupconfigkeys file for the first kde startup.

Comment 1 Olivier Goffart 2007-12-16 15:05:43 UTC

What does contains that knotify window ? Is there an error message or somethinhg ?

Comment 2 jerome 2007-12-17 13:09:12 UTC

Ok I'm able to start kde, but knotify is already crazy.
So I've saved the log, and I attached it in the topic

Comment 4 jerome 2007-12-17 13:18:17 UTC

I missed to tell you I'm using debian amd64 version.

Comment 5 Matthias Kretz 2007-12-17 14:25:34 UTC

Sorry, but the backtrace is useless. Please install libxine2-dbg to get a backtrace with more information. Also you're using libxine-1.1.90 which is not supported. Get 1.1.8 or better 1.1.9.

Comment 6 jerome 2007-12-17 14:54:15 UTC

Ok, no problem. I'll do it in the afternoon and retry a kde session.
thanks

Comment 7 Michael 2008-03-09 13:10:50 UTC

Will this do?  KDE4-svn, compiled on Gentoo Amd64.

Here's another one with xine-lib emerged with debug (so the split-debug info should be more useful)

Comment 9 lexual 2008-04-09 12:54:31 UTC

I've just hit this bug with kde4.0 svn branch.
Let me know what additional info you need to help track this down.

Comment 10 lexual 2008-04-09 13:00:53 UTC

This is the error message that comes up ad infinitum.

Window Title: Error - Knotify <2>
Window Content:
Unable to use the Xine Multimedia Backend:
QLibrary::load_sys: Cannot load $HOME/kde/lib/kde4/phonon_xine.so (libkaudiodevicelist.so.4: cannot open shared object file: No such file or directory)

Comment 11 Lubos Lunak 2008-07-21 16:23:00 UTC

SVN commit 835987 by lunakl:

Remove emitting of aboutToQuit() from KApplication::xioErrhandler() - the application
is not about to quit, it is about to fall flat on its face. There is really not that
much to do once KDE apps lose their connection to the X server. How that can happen
while the X server still continues to run is a different question and I don't know
the answer. It is quite possible it is caused by careless usage of one X connection
from several threads concurrently without proper locking.
