Possibly the cause of this issue is that the Debian packaging carries a
patch that mangles upstream default feature to enforce a specific
crypto engine: That might very well wreak havoc for any reverse
dependency expecting to be able to, well, *choose* a crypto engine.

Just a guess, and since the patch is totally undocumented - i.e. lacks
DEP-3 patch headers and is not mentioned in changelog, I give up
speculating any further...
