Specifically, when the user gets to the "Release rights" step, it seems to be applying the CC-BY-SA license regardless of what license the user has set as their default in their preferences.

The breakage happened sometime between July 15 and August 3.

Looks like this was broken by the campaigns refactoring. Specifically:

mtraceur: Could you take a look at this?

Not in the near future, but it was Yuvi's patch, maybe he has a good idea of what went wrong?

Yuvi, could you look into this?

Just got off vacation, and currently a bit sick. Should be able to in a day or two.

Hey Yuvi, did you ever get a chance to look at this?

Whoops, forgot about it and did other stuff. I'll be happy if someone else can, but if not I can hopefully look at this tomorrow?

I'm also surprised by the general lack of pitchforks and torches, considering this could be considered a big bug. But yes, tomorrow.

We "fixed" it, it seems to work now, but it won't get deployed for a little bit. I'm going to mark as resolved, but reopen if the patch doesn't fix it on Commons.

Works for me when I tried it on betacommons. Marking as VERIFIED.
