Hi all,
  I haven't compiled kde for several months.  In the meantime I had to
change my video card to an older model.  It's an old matrox G400 that
I run in vesa mode.


  A few days ago I svn'ed up, deleted all my old build files, and
compiled.  I ran dbus daemon.

  When I now run a kde4 program it crashes with the following backtrace:

(gdb) run

Any ideas?
