It doesn't do any of these calls except in the main thread. The subthread 
post distributed notifications when it wants to update the status label or 
uses a NSConnection to the main thread to ask for passwords (prompting the 
password panel), showing error (using alert panels) and stuff.

The stack trace Benhur posted shows where the crash is initiated. The 
subthread in GNUMail post a distributed notification to update the status 
label in the MailWindow. The MailWindowController adds itself as an 
observer in the main thread for those distributed notifications 
(GNUMailStatusLabelMessage). Upon reception of distributed notifications, 
this will call, in the main thread, MailWindowController: 
-updateStatusLabelWithMessage:.

This used to work perfectly for months. I haven't changed anything lately 
related to that.
