I have the same crash here (single AMD Athlon 1600), too.  It was reintroduced 
into CVS some weeks ago (don't recall exactly when, sorry).
I had this once before, which was solved around alpha4 but then reapeared. 

I have tried the procedure of uninstalling Kdevelop, before reinstalling the 
new version, too. so it shouldn't be the old problem of old plugins 
interfering. 

My backtrace is different from Daniel's though:

KDevelop is getting better by the week, thanks for it.
