I was wrong :) I had a cd <workingdir> injected into the process, now
the script is executed.

Looking at the output I don't see anything and re-trying what was
originally a problem it seems it isn't anymore. 

So the only real problem for me that is left is if KProcess really gets
ditched. Because currently Qt4 QProcess doesn't work when debugging the
app inside KDevelop3 due to unix-signal-problems (I think) with KDE3
KProcess. What I see there is that the Qt4 QProcess never sends out any
of its signals. This works fine when only running the app or when using
plain gdb and our debugger doesn't do any unix-signal handling itself.
I'm probably going to bug TT with that though, maybe they can sort that
out somehow...
