Public bug reported:

When using Xdmx as a client for Xvnc, when typing $, (as an example of symbol 
which requires a modifier key to type, Shift + 4 on a UK keyboard),
the VNC server segfaults.

Its a null-pointer de-reference, so probably not security critical.

I worked up a fix, and it was accepted in SuSE (where I originally
discovered the bug). Its reproducable on Ubuntu.
