could be a memory management issue, but so far, all I know is the
fact that my app crashes
when the method is called right after a managed object is removed.

If an object isn't retained properly and is released while other
objects still have references to it, when those other objects attempt
to access it, the program may crash. So, like Savant said, although
the debugger is telling you that your application is crashing at the
executeFetchRequest:error: method, the crash itself probably resulted
because of some memory management problem earlier on.
