Comment 4 for bug 1755380

I've now also tested 1.14.2+ds1-1 which finally landed in -proposed (the 1.14.0+ds1-1 build failed because of an alignment issue on ARM that was subsequently fixed).

The package is looking good (transcript of testing below).

And also with regard to the original format incompatibility bug that prompted this report:
