Odd crash (is it CppSupportPart or ProblemReporter at fault?)

Ok, I think I found the reason of the crash. Probably at the time when 
the timeout is fired, the m_backgroundParser from CppSupportPart is not 
yet initialized. This is beacuse CppSupportPart::projectOpened() 
creates a backgroundparser, which creates a KDevDriver in the 
constructor, which starts the event loop, timers are handled in the 
event loop, so a timer in the CppSupportPart is fired, which accesses 
m_backgroundParser, which is not yet initialized...

I have two suggestion for you to try out:

1)- init m_backgroundParser to 0L in the constructor of CppSupportPart 
somewhere before the m_saveMemoryTimer is initialized
2)- disable this timer before initializing m_backgroundParser in 
CppSupportPart::projectOpened(). (delete and recreate it for example)

Try first the 1) and if it doesn't help 2). I'd try it, but I don't know 
how to reproduce the crash. ;-)
