[imp] Error displaying messages

[Igor Stroh]

Hi there,

I dont know if it has been reported yet, but consider following
situation:
Compose mail -> add attachment(s) -> don't write anything in the body of
the message -> send it.
If the recipient opens the mail in IMP, there are neither a body (which
is correct) nor any attachments ("There are no parts that can be
displyed inline"). I know the code for this problem is located somewhere
in imp/lib/Contents.php but I can't find the piece that's causing this
behaviour. Could someone point me to the right direction? It's really
urgent, please help.

TIA,
Igor
