Pan will crash with the following stack trace if a MIME component is
too short (see example article below, following the stack trace).
I've found that adding this line

	g_return_val_if_fail (stream->position <= stream->bound_end, -1);

to the beginning of g_mime_stream_buffer_gets() will avoid the crash.
