I should add that the problems only apeared after I installed the 
debug versions of the gnustep libs.
OK I tried gdb to see whats happening. I set a breakpoint on the line 
with [NSProcessInfo processInfo]. When I step into the message call I 
end up in NSProcessInfo _gnu_process_args method. But no line number. 
The backtrace looks odd (missing the main function I'm coming from) 
and besides that claims that the method is from the non-debug version 
of the library. ldding the program reveals that it is indeed linked 
against both versions of libgnustep-base, the debug one and the non 
debug one. Strange!
