Okay, found time for some more testing. It seems that libwacom2 0.19 is probably off the hook here: the problem can be made to go away by merely switching versions of mutter (+ libmutter) for all tablets on my test bench.
Thank you for the update to 0.22, nevertheless. Doubtless it will be needed before too long. BTW, the debian/watch file appears to be broken according to qa.debian - perhaps that's why some releases weren't noticed?

No segfaults there. -- Andrew Chadwick
