Just to clarify, you got this in the console, but gnucash didn't
crash, right?  You probably got a "this report had errors" page,
right?

Yeah, the swig wrappers wrap enums as numbers, while the g-wrap
wrappers wrapped them as symbols.  For that reason, and probably many
more, in theory, saved reports from 2.0 (g-wrap) may be unreadable in
2.2.  In practice, I think most reports will work fine, but saved
queries won't.
