[BUG] : Segfault

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
I had a segfault when I browse my new mails : I clicked on the next unread
button and ... segfault ! Here is the backtrace from gdb :
#0  0x40472259 in gtk_ctree_get_type () from /usr/lib/libgtk-1.2.so.0

And I also got the same segfault when trying to directly select the
message that I attempted to reach by next unread, but I don't have the bt
for this one. Curiously while I was able to reproduce it 3 times, the
fourth time it worked without problems (I have commited changes with the
"commit all" button between third and fourth time).

For now I have no idea why this occured, but the "bad" message was just 
before the last message of the message list : has the "Last line bug" hit 
again ? ;-)
Bye
