Bug 135456

(CC'ing security@ due to the posting, though I don't consider this to be worth such attention...)

SVN commit 594522 by dfaure:

Don't crash when creating a job for an invalid URL and then calling Scheduler::scheduleJob(job),
which aborts if Scheduler::doJob wasn't called. So let's call doJob in all cases, even if we know
right away that this is an error case.
