In that case I opt to test it with Karmic once it has been released, and if it doesn't work I retest it with Karmic+1, when I happen to have that at hand. I'm not going to take the risk that someone might not work on it before Karmic, even if I tested it. The time when this gets fixed is not that crusial for me. How ever, I hope you prevent the bug for timeouting, since if the bug timeouts I might forget about it for a long period which would unnecessarily delay the test results.
