I've just started to see some crashes with this last line, mostly in stuff 
related with kate-part.

I've currently two suspects: a patch which seemed to solve some issues in 
amd64 in QJIT or gcc.

I'm currently rebuilding without the patch to check if it was the culprit. If 
it proves to be so, then I'll surely upload a new version tonight.

Else, well, I need to check what changed in gcc or other B-Ds :-/

Thanks a lot for your report and the backtrace!

Kinds regards, Lisandro.
