Finding NSTableColumn in gdb

Hi,

I am quite new to cocoa and working on a Core Data application. I have 
quite a lot of tables and now suddenly I get this error on 
[NSException raise]

Cocoa Bindings: Error accessing bound property value of object 
<NSTableColumn: 0x1bb120>: [<NSTableColumn 0x1bb120> 
valueForUndefinedKey:]: this class is not key value coding-compliant 
for the key value.

The application seems to work fine though and I cannot find any issues 
unless I break on NSException.
Is there a way to find out which table column is giving this error?

Thanks

Ed
