When using KDE, lately I get following message endlessly repeated (~ once per second) on tty1:
ASSERT: "i <= nodes" in /usr/lib/qt-3.1.2/include/qvaluelist.h (372)

Doesn't seem to happen with other wms.
Couldn't find anything related in the /var/log-files.

Any information/interpretion related to content of above message would be highly appreciated!

what is on line 372 of /usr/lib/qt-3.1.2/include/qvaluelist.h ?

372: Q_ASSERT( i <= nodes );

context:

template <class T>
Q_INLINE_TEMPLATES Q_TYPENAME QValueListPrivate<T>::NodePtr QValueListPrivate<T>::at( size_type i ) const
{
Q_ASSERT( i <= nodes );
NodePtr p = node->next;
for( size_type x = 0; x < i; ++x )
p = p->next;
return p;
}

The message is probably harmless. You could take the time to track down the app causing it, or you could ignore the message, or you could recompile QT with -DQT_NO_DEBUG

No idea how this is done (maybe fuser ???) Any hints ?
My guess though is clear, as it seems to happen only when choosing KDE as wm and KDE is known to be based on qt....

Well I could but:
1. This has not happened before...
2. I get this message about once per second all the duration of a KDE-session...
3. There might be some deeper trouble, as lately at every boot I get a message: ...was
not cleanly umounted, then it fscks and reboots....

I don't even have the sources (installed slackware-packages) +
1. Got a slow connection
2. Afraid to mess up...
3. Expectable success is questionable (or am I wrong ?)...
