I don't remember saying that. :-)  The undefined symbols would explain why
your backtraces are lacking TQt3 line numbers, without which debugging is
nearly impossible.

If this really is a [T]Qt3 problem, you should be able to revert to an
earlier version and the crash should disappear.  However, I see nothing in
the log that is close to the timeframe in question, and most of the
patches for the past several months have been trivial:

I have not yet tried to replicate this bug on any systems here.  You said
you are running this in a VirtualBox session, correct?  If so, be aware
that I have run into "TDE bugs" (crashes) before that actually turn out to
be VirtualBox bugs...
