[imp] IMAP Toolkit Crash

[Seb Belcher]

I still haven't been able to find an answer to this problem elsewhere.

The only further info I can suggest is that the crash only occurs on a 
successful authentication, a failed auth presents the login screen with 
the 'Login Failed' message as expected.

This combined with the success of the test script perhaps indicates that 
it is not an authentication problem at all but something that happens 
after authentication in IMP that doesn't get done in the test script.

Are there any known incompatibilities between IMP and Courier IMAP?  
Should I have set up any special preferences for this setup?

Thanks again,

Seb.
