--- Comment #33 from Paul "TBBle" Hampson Paul.Hampson@Pobox.com 2009-01-05 07:35:29 --- I can't see the problem in the most recent log. It appears to be working nicely, then exits.
You could try the debug version of wine-gecko 0.9.0 (on sourceforge) and/or a heavier trace level (WINEDEBUG=+relay will produce a big big log file, but it might tell us exactly what Wine's doing before the crash)
The fact that my patch fixes it suggests to me that the component probably should be mshtml, but I'm not sure about that. It might be a bug somewhere else that's being triggered by the newer Wine-Gecko.
