Segmentation fault inside the X code. not in the GNUstep code. That (assuming it's not an X bug), suggests corrupt memory or something like that. Possibly a memory error in GNUstep code, possibly incorrect/multiple library versions linked in to the binary (eg the main executable and a bundle having different versions of the same library linked). I'd suggest valgrind to look form emory corruption and looking at all the libraries linked to the executables/bindles in use (though rebuilding *everything* from scratrch will usually fix library version issues). _______________________________________________ Discuss-gnustep mailing list Discuss-gnustep@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnustep
