Should be able to add a bug watch by entering the URL

The method of adding a bug watch should involve entering the bug report's URL, not choosing a bug tracker then entering a bug number.

<ryanakca> IntegrityError
<ryanakca> A server error occurred.
...
<jamesh> what data did you enter into the form?
...
<ryanakca> jamesh: kdebase and http://bugs.kde.org/show_bug.cgi?id=129267
<jamesh> did you get an OOPS number?
<ryanakca> nope
<ryanakca> just the two lines above...
<mpt> ryanakca, did you enter the whole bugs.kde.org URL, or just the bug number?
<ryanakca> whole URL
* ryanakca wonders if he's being ignorant
<mpt> ryanakca, at the moment you need to enter just the bug number
...
<mpt> We should accept the whole URL, but we don't yet
<ryanakca> kk, fixed, thanks
<jamesh> we should definitely have something better than "integrity error" if you enter a URL there ...
<ryanakca> yes... :)
<ryanakca> it's confusing... maybe a "We're sorry, but we do not accept URL's at the moment, please..." page
