Andrew Halberstadt f354075c7a Bug 1434430 - [flake8] Fix blank 'except' statements r=rwood
This is a new issue that gets linted with flake8 3.5.0. Basically you should
never use a blank except: statement.

This will catch all exceptions, including KeyboardInterrupt and SystemExit
(which is likely not intended). If a catch all is needed, use
`except: Exception`.  If you *really* mean to also catch KeyboardInterrupt et
al, use `except: BaseException`.

Of course, being specific is often better than a catch all.
