My KDevelop has been crashing on startup for a few days now. There is no 
time to attach a debugger.

That doesn't work now. The kdevelop process forks and runs a new kdevelop, 
and gdb stays watching the parent. If I set follow-fork-mode to 'child', 
when the child kdevelop runs 'uname' during startup, I'll be debugging uname 
(which promptly quits) while kdevelop crashes.

kdevelop1 -> kdevelop2 (with env var set) -> uname

How do I debug the middle process?
