Can't categorize using user ID 11

[khatchad]

I tried to add a categorization for 05b6a643d1aa82be3acf8324181595d8abff1eb1 (I am on b910532c), but I received an exception. I just entered is func fix = false without any other data to the form.

Looks like the categorizer isn't being looked up correctly, at least for my user, whose ID is 11.

[khatchad]

This is probably a regression.
