[texworks] texworks apparently crashes on closing

Dear all,

one of the revisions between 640 and 649 must have broken something for me.
Texworks compiles fine, but when I try to run it I get appended backtrace.
I'm running Ubuntu Lucid with Qt v4.6.2. On the same system r.639 compiled and ran fine.

Cheers, Peter
