Hot fixes should be sent to kde-packagers as a patch, or even better as a commit number.

Example:

"Dear packagers, we found a bad bug in kde-foo that causes the following terrible things to happen.
Please apply commit abc123 to your kde-foo packages and distribute this new version to
your users as soon as possible."

I don't think we want to respin tarballs for bugfixes.  To my recollection, we never have.
