Created attachment 27500 [details] plasma-filewatcher.kcrash In 4.1.1 I find this happens only if I configure the plasmoid by clicking the big "configure" button in the middle of the plasmoid. The file gets displayed, but mousing back over the file watcher causes the crash.
I can confirm this with my own plasmoid (means, it's not specific to the filewatcher applet). Is this possibly a Qt bug? It usually works if I log off and on again (thus restarting plasma) before configuring the applet.
See also https://bugzilla.novell.com/show_bug.cgi?id=436361, using 4.1 as well.
According to Aaron Seigo, this is a Qt bug which is already fixed in qt-copy and in the coming Qt 4.4.4.
I also had a crash with the file watcher plasmoid but the backtrace is a little diferent. It happened while moving the plasmoid: Application: Plasma Workspace (plasma), signal SIGSEGV Using host libthread_db library "/lib/libthread_db.so.1".

qt-copy revision 882016 and KDE revision 882432. Immediate crash when starting to move an applet with similar callchain again. So no, it doesn't seem to be fixed in qt-copy.
0260-fix-qgraphicswidget-deletionclearFocus.diff seems to have done the trick. Have not seen any reoccurance since that patch was applied to qt-copy. Guess this can be moved to fixed now.
