attempting to disable languages in a project results in an error page.
the languages remain enabled.
Steps to Reproduce:
1. select a project (e.g. "ovirt-test")
2. select a version within the project (e.g. "master")
3. select "Manage Languages" from the "More Actions" menu in the "Languages" section.
4. select a few languages and select "Disable"
an error page with the following text appears:

[Report this problem]
When navigating to the project's version's languages again, the previously selected-to-be-disabled languages are still enabled, so the action actually failed.
the selected languages are becoming disabled (i.e. the action succeeds), no error page is displayed.
