Because the value they provided was perfectly valid (the file/directory *did* exist), so the caller's request was reasonable. It's the system(/ its (lack of) configuration) that failed the caller in finding an opener application. The "fix" after encountering the exception is to add an association to the system configuration (and/or install a new application), not to pass a different path to the function.
IMO, it feels like an EnvironmentError or RuntimeError of some sort; hence the current use of OSError.
(Or NotImplementedError, but we're already using that exception to indicate a different failure condition, so that's out.) |
