It does crash when I do this, but in a different place. I'm unassigning this, 
as it probably isn't a text system issue (or at least not only a text system 
issue). A backtrace with debugging info would be helpful.

I try a fresh GNUstep and ProjectCenter both on FreeBSD and Linux.
It works fine on FreeBSD, but segment fault on Linux.
So weird that it is OS-dependent.
But from my experience, FreeBSD can tolerate more memory leak than Linux.
I even deleted the installed GNUstep and downloaded a clean source code from 
CVS.
If no one can reproduce it, it may be a problem of my Linux machine.

Which version of -gui is this? It looks like a bug that was fixed in cvs 
2003-04-03.
