You have access to cooler tools than I :)

That somehow doesn't surprise me.  I can't imagine how the spurious data got in

I tried just a "cat winmail.dat | tnef -t" command on one of them and it
doesn't segfault or crash, but it didn't return anything on stdout either like
it is supposed to (unless I add the --debug).  So it is certainly munged.

I did some additional research, unfortunately we *HAVE* to use the tnef plugin,
because outside people really do send us stuff in that horrible method (rather
than just attaching files directly).  I am really caught between a rock and a
hard place now.

Would this issue really only be with the tnef plugin or ALSO with claws?  Yes,
the plugin depends on ytnef which is crashing, and that causes the plugin to
fail... that is one bug (which I think is higher than "normal" priority).  But
Claws should not crash in this case, wouldn't that be another bug?  Should I
create a new one for that?

You are the assignee for the bug.
