GUI bugs?

[Ludovic Marcotte]

Hi,

I've just finished integrating Pantomime to GNUMail.app but I'm facing a
small problem when I'm using my IMAP (or POP3) classes.

When I'm using my generic interface in Pantomime for accessing
Local folders, everything works perfectly.

When I'm using my IMAP implementation, the application starts correctly,
and displays the first message correctly like you can see in the following
screenshot:

If I click on the second message, the body of the message is fetched on a
socket by Pantomime and I get a segfault with the following stack trace:

Program received signal SIGSEGV, Segmentation fault.

If I try in POP3, it does exactly the same thing as in IMAP. It shows the
messages. If I click on a message, I get:

I've searched for the problem in GNUMail.app/Pantomime and I can't find
it. I think it is in GNUstep's GUI but I haven't looked in details.

Anyone has an idea that could help me solve this problem?

Thanks,
                Ludovic


PS: Note that I can provide you a snapshot of Pantomime and GNUMail.app
together with guidelines on how to reproduce that error.
