So far, this evidence points to a bug in Mozilla rather than in Wine.  It
may very well be triggered by a bug in Wine..

Mozilla's passing an apparently invalid pointer to WideCharToMultiByte. 
Question is, where does this come from?

Running with WINEDEBUG=nls may give a clue what string it's trying to
convert, which may give some indication of the problem.  Running with
WINEDEBUG=relay will probably give a better clue, but be prepared for a
huge log.  But since the Mozilla source is available, you may be able to
hunt it down more easily using that.

Well, I included a bit of the relay trace I did in my first email, and
it includes the first occurance of that strange memory address (or
anything near it for that matter).  Since it's being passed into wine
from Mozilla, I guess you're right and it is a problem within Mozilla.

While this is always a possibility, it leaves one wondering.  Why does
Mozilla work in Windows XP but not in xp mode in wine?  Just because
Mozilla is passing a bad memory address doesn't mean it's a bug in
Mozilla.  For example Mozilla could have requested some information
from wine and we gave them the bad memory address.  Then they call
WideCharToMultiByte with the bad memory address we gave them.  Your
best bet is to find the first place this bad memory address pops up. 
Having a copy of the Mozilla source would probably be a good thing for
this exercise.

Is the Mozilla Installer Installshield or MSI based? Otherwise is it open
source? Perhaps an easier way to backtrace the problem?
