The problem is that the path to UNIX sockets are limited in length and you are
probably hitting that limit. The base classes take care of avoiding that but I
did hit this problem in a custom recipe that was using gpg directly.
I solved problem in the task shell function that was calling gpg by using a
host temporary directory (/var/tmp/...) as a throw away GPG home directory.
gpgdir=`mktemp -td ${PN}-gpg.XXXXXX`
install -m 700 -d $gpgdir/home
gpg --batch --homedir $gpgdir/home ...
...
rm -rf $gpgdir
Hope that helps.
