[BUG REPORT] balsa crashes upon receiving new mail

[Nuno Monteiro <nuno itsari org>]

Hi guys,

I reported this over the weekend, I think it went unnoticed, so I'll just 
nag you again ;)

Ever since I upgraded to 1.3.3 cvs (which happened over the weekend, when 
Pawel fixed the _N / TRUE / FALSE clash), I have been able to 
successfully crash balsa just by receiving email via POP3. I just cvs 
update'd to see if there was any changing in that front, and indeed there 
is. Previously, Balsa would crash if there was any mail to be delivered 
to any of the mailboxes I had opened at the time, I mean, it checked all 
accounts just fine, download the mail, and then when the popup window was 
reading "Local mail", it crashed. With today's CVS (as of around 22:00 
GMT march 12th), the behaviour is a little different - I check my  mail, 
there are messages delivered to mailboxes I have opened but Balsa doesnt 
crash, instead it doesnt show those new messages in the index, and while 
on that state, it will crash if I try to open any message (double click 
on it, to open in a separate window). If I close and re-open the mailbox, 
it'll work as expected. The GDB trace is as follows:

Program received signal SIGSEGV, Segmentation fault.

As stated previously, all the mailboxes are Maildir type, and mail is 
filtered through procmail upon receiving.

Ok, that one is reported, but there's two other things I feel are worth 
mentioning:

First, Balsa is not properly updating the Unread Messages count, in the 
mailboxes pane. If I open a mailbox with 100 unread messages, it'll stay 
at 100, unless I either (a) close and re-open that mailbox or (b) read 
(or mark as read) _ALL_ the messages.

Secondly, there is some misbehave in the dynamic signature changing, when 
cruising through different identities. I have an identity whose signature 
is a perl script that spews out random quotes. It works fine of course, 
but if I try to change to another identity afterwards, the signature wont 
change. This only happen with 'executable' signatures, If they are plain 
text they'll be changed without problems. But once you change to an 
identity whose signature is executable and try to change the identity 
again, the signature will remain of the previous identity. God, my 
phrasing is confusing, too many instances of 'signature' and 'identity' 
in the same sentence... Please bear with me, I'm dog tired and half 
asleep :) Anyway, if you guys cant figure out what I'm mumbling about 
I'll try to re-word it in a more civil manner tomorrow. Right now, I'm 
going to bed.

Thanks :)
