Merge branch 'master' into 'master'
fix two bugs
First bug is with lots of QR Code readers, they don't respect custom URI schemes like `fdroidrepo://` and just force all URIs to be `http://`. A slight tweak makes it possible to use a QRCode to configure a repo using all of the major ones I could find (I tested with 8 different apps).
The second bug is a simple crasher bug.
