#2 App crashes if source URL changed at just the right time

[Michael]

If the selected source URL is changed precisely between
the time where the app pulls down the current cache and
when the app actually goes to parse the data, it will
probably crash. This is because the app then thinks
it's parsing the new source type rather than the one
that it pulled down.

This also seems to happen when the app detects too many
errors and switches to a different source. If the new
source is of a different type, the app will usually crash.
