Crash when viewing github page from settings

Via Google Play Console. Has occurred 400 times in the last month (2nd most of any crashes). The title of this issue is my interpretation of the stack trace - I have not witnessed it myself:

Perhaps related to Android M requiring you to specify which package you want to handle the intent (even if just hoping for browsing a URL): https://stackoverflow.com/a/67485825.

It seems like the worst offender (#65) is fixed now judging by reports in Google Play. So that means this is now the most commonly logged bug. It is annoying, because it stops people coming here! I'll take a look at it and see if I can reproduce and then fix it.
