Not sure, if the python bindings should simply drop and reopen a
database connection in that case? But I am not sure if libnotmuch.so
still simply exits on such an error case.

The proper fix, and a reason why I am not immediately hacking around in
the python bindings is that notmuch the library would actually return a
proper error value rather than print to stderr and quit.

Happy to receive suggestions on how to handle this best from the python
side of things.
