[CRASH] : deleted messages

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
here is the crash I have when I manage to have a message displayed as 
deleted (ie with the trash icon) (usually I get that because I'm testing 
filters that move messages). Until then no problem, but when I click on 
"commit all" and then click on one of the messages marked as trashed I get 
a (really bad) segfault :

libbalsa_mailbox_commit: rc=0

Program received signal SIGSEGV, Segmentation fault.
0x80b5e98 in libbalsa_message_has_attachment (message=0x89960b0)
     at message.c:901
901         if (msg_header->content->type != TYPETEXT) {


I can't do backtrace because I have to kill gdb to unblock X that is 
completely stalled after this segfault!!!
This is reproducible, it's always the same crash. It seems that the 
messages get freed when we commit changes to mailbox but that the index is 
not aware of that. I'll try to dig it a bit, but I'm not actually 
comfortable with this part of the code yet, so if someone who knows better 
could also try ;-)
Bye
Manu
