Yep: sounds like queued-up gtk callbacks are being executed when
gtk_dialog_run() is executed (as part of doing the alert box) since that
effectively runs gtk_main_loop().
There's lots of "interrupt" (callback) type stuff related to updating the
packet display going on with the our packet_list widget which I've never fully
grasped.
There may be a way to still use report_failure() in the middle of doing a
dissection and not get thrown into the swamp, but I don't know how.
When the internal error occurs, is it possible to just put an error entry onto
the dissection tree (using expert... or whatever) ? (I haven't actually looked
at the code).
