 This error is caused in a SHP feature reader due to the assumption that
 the dynamic cast of an expression always returns a certain result.
 Therefore, the resulting pointer is used without checking for NULL and
 hence causes an issue if - like in the case that resulted in this ticket -
 an expression function is used in a filter.
