MainWindowExample crashes on exit #109

Closed jkdoug closed 10 years ago

jkdoug commented 10 years ago

After compiling Qtilities and QtilitiesExamples, I simply ran the MainWindowExample and exited it. No other action was required to make this error occur.

Hi, thanks for the report.

This is a duplicate of https://github.com/JPNaude/Qtilities/issues/100. I will close this issue since its a duplicate.

The crash is complex and I've spent a few hours trying to fix it, however since its in the debug plugin which is really only for debugging, it should not happen in release code.

I'll try to spend some more time on it.
