gpgme/lang/qt/tests/t-tofuinfo.cpp
Andre Heinecke 2c063a8d60
qt: Handle if gpg does not support tofu in test 
* lang/qt/src/t-tofuinfo.cpp (TestTofuInfo::testSupported): Treat
it as unsupported if secret keylisting already fails.

--
The likely cause of this is that the agent can't be started
because the trust model is unsupported. Other tests check
that keylisting actually works.
