Search & Replace Error

This doesn't cause me too much trouble, except the trouble of hitting the 'Find' button again, but thought I would mention it.

Every once in a while, when I search for something the following comes up:

calibre, version 3.3.0

As I mentioned, after dismissing the error message, clicking 'Find' again works perfectly.

That's a very odd error, I dont know how it could happen, but I have added a workaround for it.
