Based on this and on a suggestion Ricardo made on IRC, I passed
“-padding 10m” and that solved the problem.  \o/

I suppose you’ll have a scientific explanation, but I’m happy this
simple hacks works (and indeed, the documentation of “-padding” suggests
that this kind of problem is not uncommon.)

Thanks to both of you!
