[Qt-creator] Crash when Options dialog is closed

[Eike Ziller]

Hi Diego,

thanks for your report. The crash should be fixed in the 1.2 branch  
(8161acac8bc747bde84eca488e88c2c802a6aa7f),
but the change was not merged into master yet.
(The merge should be up on public during the next 12 hours)

Regards, Eike
