Doesn't work either. It seems like the kdevelop.bin process detaches
completely. And yes it does have execv() already in the code. 

It works however if I only start kdevelop without gdb, then it doesn't
detach.

@#%#$$@!$@#$~!!!@@!! I had follow-fork-mode set to child in my .gdbinit
:) Which made gdb follow the first qmake call and when that one exited
gdb exited too... Thanks for hitting me with a brick wall into the right
direction.
