Well ok... But... well... that still doesn't solve it does it?
Thanks for the help everyone. I'll just pray it doesn't happen with anything crucial.
It the bug could be isolated and reproduced in a single blend file or through a precise number of step, we would be able to look into it rather easily, but for a random bug, someone would have to dedicate a lot of time to try and reproduce it (which might not ever happen if it's related to some hardware or 3rd party software problems).
