I think that's a bit optimistic. To be honest I don't come across that many bugs in open source software. Google and Apple products, yes, but I generally don't have access to their source. Right now there are just a couple of open source bugs that are annoying me, but each of those would likely take me at least a few weeks of full-time work to track down. IMO you're much better actually building something impressive rather than fixing a bunch of bugs if you're looking for a job.
