I can manually enter a Base32 code and FreeOTP works fine, but when I
try to scan a QR code it pauses, with a blank screen, and then says
"Unfortunately, FreeOTP has crashed".
Part of the problem may be that I don't know the exact format required.
Currently I'm just using qrencode to generate the QR image with the
input string being the Base32 text (i.e. exactly the same string that
works fine when I enter it manually).
I'm running FreeOTP 1.3 on a Samsung Galaxy S3, Android 4.3.
