NSOutlineView / GSArray exception linux-ppc

[Riccardo Mottola]

Hi,

I just build a complete, from scratch install on linux PPC, debian, to 
test that everything works there.

First, a confirmation: installation is really a no-brainer. Once you 
have the dependencies, which I had, it is a matter of configure && make 
install. Since we always get criticized for that, it is reassuring that 
everything actually works.

I start now checking how various apps perform.

I have GNUMail crashing as soon as I try to set up an account (sowmthign 
which, even with all the bugs, I have done on many other systems)

It hangs as soon as I edit the acocunt:

the excpetion I get is:
<NSException: 0x103c5180> NAME:NSInvalidArgumentException REASON:Tried 
to add nil to array

I don't get this on other architectures, but it may be a chance... what 
is going wrong?

The IMAPView is setting up an NSOutlineView with the 
AccountEditorWindowController as parent and datasource. It may be empty, 
but why is the crash happening inside the gnustep class?
