Crash after refresh, view and return

Hi,

The app always crash when the following receipt is followed.

1. Open the News program from "cold", i.e. without having it in the background first.
2. Open the podcast folder/category in the News program.
3. New podcasts/entries are added.
4. Open an entry and click *back*, to return to the list of all new podcasts/entries.
5. The News program crashes.

It does not happen if new entries are not added in step 3.

I hope it's clear enough. It might be related to #535, though I experience the crash when I return to the overview. I'm happy to provide more details.

I'm using the latest F-droid version.

Thanks,
Rasmus
