no, testing was complicated because triggered only by error conditions.

My guess is that since an object is used as a "key", if for some reason 
the object gets dealloc'd outside the map, the key becomes invalid (I 
understand what while values do get retained on insertion, keys are not).
I thus decided to retain the key at every insertion and release it later 
on removal. Seems to work, but since I found not a valid way to trigger 
this bug (except for running GNUMail in gdb for hours) it is more a 
theoretical fix.
