Running locally in debug mode

When I add an object, I get this traceback:

smart_unicode is None

This seems to be some kind of magic import related bug, since there doesn't seem to be any natural way for the symbol 'smart_unicode' to be assigned the value None.

A hack patch that fixes the problem follows (though it would be good to properly diagnose the problem)

Fixed formatting. Please use WikiFormatting and preview before posting. If this is recreatable on your machine, I suspect something is corrupt in your install. Un-installing and re-installing (I'd suggest a more recent level than 1.2 beta, though I don't recall that 1.2 beta ever had this particular error reported against it) may fix the problem. Plenty of people are able to add things via the admin without error...this is not a problem people have been reporting generally, so whatever is wrong is likely specific to your setup and most properly fixed by fixing that, not changing Django code to include an import were it should not be necessary.

Closing invalid; this report doesn't contain enough detail to reproduce the problem, and as Karen suggests, it is suggestive of a corrupt install. Feel free to reopen if you can provide specific instructions for reproducing the problem.
