 I guess you need to compile wx with --disable-exceptions if you do it for
M. It would be nice if we could override wxUSE_EXCEPTIONS before including
wx headers but I don't think this works currently.

 The simplest would be to stop using -fno_exceptipns when building M, of
course...

Should I commit disabling -fno-exceptions (it helped to compile) or should
we wait until we can override wxUSE_EXCEPTIONS?

 This is really strange, m_Cell may not be NULL here (it's checked for just
above) so apparently it's a dangling pointer but I don't know how could
this happen and there have definitely been no recent changes to wxHTML
which could explain it. I guess I need to debug this myself... Does it
happen with any (HTML) message?

 Thanks,
VZ

With at least two completely different messages. I can send a sample to you.

When this message is selected and previewed when I've just started M, it is displayed
correctly, but if i select another message and then select this message again,
M crashes.
