Do I have a red-hot "it's probably this" idea that I have some confidence in? If so, I probably chase that one in depth first, at least to the point of being able to confirm or disprove.
In the exact scenario you gave, I'd probably do breadth-first, because I don't know if it's OS-specific or not, and the possible causes are different depending on whether it's Linux-only or not.

It depends.
