Wow, thanks for finding this!  it does look relevant.  I'll poke around
in cowbuilder and pbuilder to see if there's a /dev/pts issue i can sort
out there.

But...  should gpgme require the existence or proper configuration of
/dev/pts in some particular mode to be able to work?  It seems to me
that a system without /dev/pts at all should still be able to use gpgme,
