Every now and then (but certainly not always) when I execute C-x C-b the screen freezes, the message <<<Press Return to bury the buffer list>> displays at the bottom but no buffer-list is displayed and my only way out is to xkill emacs. Obviously this disrupts the work flow somewhat.

When I type or scroll left or right the cursor leaves a trail of identical character such as bbbbbbbbbbbbbbbbbbbbbb. This is purely visual, if I switch to another buffer and back again the artefact is no longer there (except right next to the cursor). Again this is far from desirable. I believe this is a related bug because it seems once it starts doing this and I call the electric buffer list then the freeze bug is guaranteed.

Did you try Emacs 23?
