When I build the fetch request by hand, it seems to work. When I execute a saved fetch request, I get the following error:

2006-07-20 15:15:20.087 drachma[849] *** -[NSKeyBindingManager subentitiesByName]: selector not recognized [self = 0x33f6b0]

or one like it. Sometimes the class which does not recognize the selector is a dictionary, other times a string. Sometimes I simply get a SEGFAULT or BUS error.

This sort of error is highly characteristic of incorrect memory handling. Try running your application under MallocDebug, and check your code carefully for overreleased objects.
