Sorry, I was imprecise--I meant that the object that Balsa uses to
represent a message had a NULL value for the pointer to the object that
represents the message content--quite different from having no content!

If the new message is inserted into a thread in which some messages are
selected, that can result in a message being deselected, so there can be
interactions between new mail arrival and message selection. But it's not
obvious from the code how that could result in the NULL pointer problem.
For now, the only fix that I see is what we have currently: issue a
warning and continue without retrieving the message content.
FWIW: the code to detect and warn about the issue, avoiding the crash, was
installed in August last year, so the possibility of a NULL pointer was
known back then. However, I don't recall seeing the warning, so possibly
some other change in more recent Balsa has fixed the underlying problem.
Best,
Peter
