Sounds like the shared memory code is failing without noticing it. Which
version of GNUstep is this? What system? There was a similar problem on
some systems if a segment was marked for destruction too soon, but it
was fixed 2002-08-23. Some things worth trying are (in
back/Source/x11/XWindowBuffer.m):

* line 174, change 0700 to 0777 (a potential security problem, though)

* line 226, remove the shmctl() call (will leak shared segments; remove
them with ipcs or equivalent)

If any of these help, please let me know and I'll try to make a proper
solution of it. As a temporary workaround, you can comment out the if on
line 147 so the non-shm code always gets used instead.

Apart from getting and installing fonts, there is none, and none is
necessary (in theory, when things work :/ ).
