What's up with this?
I keep getting similar crashes every now and then...

I've been suffering from this in both Hoary and Breezy, it's also occured on 
all three platforms (x86, AMD64 and PPC). I really don't know what causes it, 
it just happends to different KDE apps in Kubuntu every now and then.

The thing is that it's starting to drive me nuts, I've been waiting and 
waiting for it to go away... but it just won't. :-(
Will it in Dapper? I dunno...

Any solution, hints or ideas?
I really otherwise love Kubuntu, and it's the only distro (along with Ubuntu) 
that I know well... I'd use Gnome to avoid these crashes, but as I use many 
KDE apps it'd still haunt me.

If I don't get this resolved I'll have to go for something else...
PC-BSD, SUSE, I don't know what... and I'd rather not have to learn another 
system from scratch... Maybe a dist-upgrade to Dapper would save me... maybe 
it'd just end my misery by rendering my system useless, forcing me to go with 
one of the others... Hmmm... which one? It needs to have decent package 
handling along with a decent amount of available packages.

  cheers, Simon
