Wow, those are really unlikely bugs.
In all seriousness, the likelihood of the first thing happening is extremely low (winning and dying at the same time). I doubt it's related to the linux version, but nobody has run into that yet (or at least not reported it yet).
In terms of clipping into the door, if you have a way to repro that, that would be appreciated. You definitely are right that that shouldn't happen, but I can't duplicate it based on your description, and nobody else has reported anything similar, either.
Restarting the game or levels is indeed frustrating, but the odds of you running into two of these kinds of bugs is really low; each one individually is really unlikely enough on its own.
