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

Well, my third is slightly different, but I was mainly posting to 
confirm that it wasn't already fixed. Since crash #3 is today's svn, I 
think that counts as a 'no'. (Or did you mean because I quoted the stack 
dump? It isn't "actually" from the previous e-mail; quoting it turns off 
Thunderbird's wrapping, at least while composing.)

Yes, these are two crashes in less than 10 minutes. I am getting about 
15 seconds of work done before KDevelop goes bye-bye. (BTW the project I 
am working on while seeing this is kdelibs 3.5.5 release as from 
kde.org; no distro changes, although of course I am playing with 
plastik.cpp.)

WTF happened to CppSupportPart in svn that it is suddenly making 
KDevelop unusable?

'Start in KDevelop' doesn't work (possibly due to the known debugging 
bugs), so I am going to try to run in gdb to see if I can do any more 
debugging, but I'm not familiar with CppSupportPart at all...

Anyway, here is #3; I'm not sure if quoting makes a difference so I'll 
forego it this time.
