The "patch" keyword stays enabled even when all patch files have been removed from the issue. See http://bugs.python.org/issue2394 for an example.

That's intentional or at least unavoidable. There is no automatic procedure to clear the keyword, and it isn't obvious that there should be one: it may be that a patch is in one of the messages, and/or that the keyword was manually assigned.

The problem is that when you try to clear the keyword manually, it
doesn't work.

I think I removed a patch keyword recently.  Antoine, is that a form UI issue?  Does it work with other keywords but not patch?  Can you open a test report to test?

I seem to remember that the only way to remove all keywords (ie: remove the last one) is to select '- no selection -'.  I think there might be a bug report about that, but I'm not sure.
