Device was in airplane mode and i tried to manually check for updates (by swiping down)
on the first try app closes
on the second try crash report

@lberrymage probably #322 will fix this, too.

Proposal:
Some kind of feedback/info message for the user.

For example with the app FFupdater you can swipe down as much as you want (no crash), but also gives a message at the bottom: internet connection temporaly not avaiable, try again later, when user is in airplane mode/ no internet and swiping down.
