Hmm, it could be it. But it's still odd. It happens whenever I run aptitude 
and try to install/remove stuff. Aptitude seems to exit cleanly but there's 
the lock after I start any package manager INCLUDING aptitude. Last time it 
happened, I did not even update the database... Usually, the notifier pops up 
when the database is refreshed, but I don't like to use it anyway.

One other problem I'm facing with aptitude is that it constantly tries to 
remove most of the packages (whole of KDE, OpenOffice, python, etc) claiming 
they are no longer needed... I just press + for the entire group and the 
problem if fixed for that session, but next time I launch aptitude, it again 
tries to remove the same packages. Any way to fix that?

Apart from memory test, I would rule out any other hardware trouble. I changed 
IDE cables a few weeks ago and they work as expected. I also tested the drive 
itself because I'm using the same disk I recovered lost photos from. I had to 
check it during recovery. As for CPU/Case ventilation, I installed two extra 
fans into the case, so I doubt it is the CPU overheating.

I will run memory test this weekend, and see if this is causing the trouble. I 
have a RIP Linux with memtest on it.

At this moment, Kubuntu seems to run normally... for now. After a recent 
update of libqt3-mt package, my uptime is more than 16 hours, which is quite 
promissing. Maybe that was causing trouble?
