Segfault in XGServer(X11Ops)

[Marc Brünink]

Hi all,

I'm running a GNUstep application on a remote X11 server. The 
application opens up etc. However in the majority of cases it segfaults 
if I try to select anything in the menu.

Anyone had the same problem? Any suggestions except learning xlib :-) ?

Thanks
