Why gpg 2.1.9 cannot export secret key without passphrase?

[Andrey Utkin]

 $ gpg --export-secret-keys
(pops a Xorg dialog window from my console, driving me nuts)
(i give empty passphrase)
(it asks me whether i am sure I want no passphrase)
(I say yes)
gpg: key XXXXXXXX: error receiving key from agent: No passphrase given -
skipped

Why is there such a _policy_?
Maybe I am lost and I am using Windows which re-asks everything and
still refuses to do what I want?
