Bug 56779

When i open gideon, the previous project is loading. If during the parsing of the project 
i load a project in the Open Recent Project menu, kdevelop crash.  
 
here is the end of the bt (i'm sorry, there are no debug info)

I experience the same crash as Olivier, and i have a bt with debug info :) here goes. It's not quite 
the same, but close.

CVS commit by dagerbo: 

Restructured parseProject() to not require processEvents() calls.
This should fix the case where closing the project during
the initial parsing results in a crash.
