Does ist help, if you assign it this way instead:
self.context = theContext;
In your original code you're directly accessing the "backed" instance variable
instead of going over the property, so maybe your property-declaration is
ignored in this case.

For me this sounds like an "overrelease" or "access after release" problem.
