Bare except :( At the very least, this should catch `Exception`, but probably better to only catch expected exceptions. Some poking around suggests that perhaps `OSError` is the only thing likely to be raised here.

In any case, it would likely be useful trying to debug what is going on if this failed, if some more meaningful error was returned. The default behavior of an exception is to propagate it (at least partially) to the master, so catching here make debugging harder. (That isn't to say that it shouldn't be caught, but that something useful should be done with the information contained in it.)
