No I haven't and the tracelog indicates or seemed to indicate when I 
quickly peroused it to be purely a thumbnail issue. I have disabled the 
thumbnails after much ado (they are called tooltips) although I must say 
I do miss them and I don't like it this way. But a similar thing seems 
to happen in the KDE menu and it also causes the same kind of crash I 
think, it is just less now than before.

Not completely satisfactory at all because I find myself hovering over 
the tiles to see the thumbnail so it was in fact useful to me. But there 
is a bug in there that causes the crash -- I think -- and I submitted a 
bug about it.

Here are some of the latest traces in the thread that crashed it.

You can see the offending Plasma function is probably 
Plasma::WindowThumbnail::bindGLXTexture and this is probably purely a 
plasma framework problem but I can't tell.

So now I don't have my thumbnails as they would crash it constantly and 
I guess I have to thank Nils for pointing me to it or at least 
suggesting what it might be, but I had to look at the trace to get a 
clue and I'm not really happy with turning it off, I might just as well 
replace the card you know (and do some real troubleshooting, for if the 
problem remains, then it is not the card but it is going to be the 
software upgrades I had).

Regards.
