strange issue with Mutable Array

[Riccardo Mottola]

Hi,

Sebastian sent me a stacktrace of GNUMail+Pantomime crashing for him.

Now the issues could be many leading to the crash, but I do not the understand the stactrace, which I paste below.

Frame 2 comes from this code:

[_properties removeObjectForKey: theKey];

can removeObjectForKey fail in a bad way ?

 theKey is a constant, it comes from line 531;
[self setProperty: theBaseSubject forKey: @"baseSubject"]; theBaseSubjet is explicitely nil. The code seems quite simple in this regard. _properties itself is allocated/retained in init and released at the end. Any suggestions? Besides that the whole Message is for some reason not properly retained or allocated, thus leading to a garbage situation- Riccardo
