Don't get the pinentry for passphrase in some contexts

"debug-pinentry" in gpg-agent.conf would give you more info.  Adding
also "debug ipc" will show you the communication between gpg and
gpg-agent; that is what you strace shows.  Use "log-file FILE" to set a
log file and remember to reload gpg-agent.

The agent tells gpg that a pinentry has been launched and gpg
acknowledges that ("END").

The agent tells you that the Pinentry canceled the operation.  This is
usually due to clicking the cancel button.  Some older versions of
pinentry use cancel as a catch all error from pinentry.  Modern versions
of gpg running with "-v" will print a line identifing the pinentry used
and thus reveal possible problems, for example a missing GPG_TTY
envrionment variable.

This returns some data ;-)
