BTW this is a regression from 20050211. There this didn't happen.
Strange thing is, it still happens with 20050211 if I don't remove the
riched20.dll from 20050310 (wich obviously is new there). Unfortunately removing
if from 20050310 does not work.

Additional Info:
I get this message, before anything goes wrong.
fixme:richedit:RichEditANSIWndProc EM_AUTOURLDETECT: stub
fixme:richedit:RichEditANSIWndProc WM_SETFONT: stub
fixme:richedit:RichEditANSIWndProc EM_EXLIMITTEXT: stub

And, I can crash it by editing more than 22 characters and not touching the menu
at all, resulting in this stack trace:
