[Adium-devl] Proposed minor release schedule

[Graham Booker]

I remember looking at this, but unfortunately, I can't figure out  
what causes it.  I see exactly what the crash is, but not how it  
could happen.  Essentially, addr is an invalid pointer, but just  
before that, it is set to a newly malloced memory.

I really need a sure way to reproduce this so I can see what is going  
on (or a whole lot of printf debug messages if someone can reproduce  
it occasionally).
