strange list behavior

[Matthew M Murphy]

Group: 

I'm receiving an interesting error, triggered by the following line of
code which is located in my bugs' step method:

    printf("my lexList has %d elements \n",[lexList getCount]);

In my bug.h file, lexList is declared as follows:

    id <List> lexList;

The strange part is the error I get at runtime:

address@hidden/bug
my lexList has 0 elements 
*** event raised for error: InvalidArgument ***
function: _i_Object_s__doesNotRecognize_(), file: DefObject.m, line: 872
Morpheme does not recognize getCount*** execution terminating due to error
Symbol.m:173 -[Error(c) _raiseEvent:]
Aborted           

The list contains morphemes, but I am not trying to send getCount to a
morpheme.

Below is a backtrace from gdb:

I'd be interested in any suggestions that anyone might have...
