Re: [bug]org-mode with flyspell-mode freezes emacs

[Carsten Dominik <dominik@science.uva.nl>]

Apologies for my previous message in which I said I could not reproduce 
this error under gdb.  This was a mistake on my side, caused by an 
alias expansion of the command emacs that make "gdb emacs" refer to 
emacs 21 instead of Emacs 22.

Anyway, I do now have a backtrace for this problem.  Can anyone extract 
something useful from this?

Thanks.

- Carsten
