Agent crashes when sending article

Some time ago I posted that Agent crashes when sending an email. At this time
the crash was sometimes quite frequently and sometimes it worked well for an
extended period of time. Now I found a scenario which will cause this crash
rather reliably (it failed only one time for me when I tested it).
Compose an article with a non-existent newsgroup., messagetext and subjectline
doesn't matter I think, and then send this article with <ALT>-S (for
Send-Now).
When the crash occurs ebx contains a pointer that is pointing to some invalid
address (actually it is a string instead of a pointer) which is subsequently
referenced. On each crash the pointer and it's content is the same.
I already run agent with "wine -debugmsg +all" and got a rather huge trace
(about 500MB) so if you need any info I can extract it from this. I tried to
anlyze the problem but I have problems interpreting the trace so it doesn't
tell me much. I would investigate this myself but I need some input how the
best way to approach this. winedbg is not much help to me for now. Or can you
set memory access breakpoints like in Softice?
