Gpgsm 2.1.8 Windows 7 32 bit.
Noticed this because kleopatra brings up the "the search result has been
truncated" message even if only one key is shown.
echo keyserver ca.intevation.de::::o=Intevation GmbH,c=de > %GNUPGHOME%/gpgsm.conf
gpgsm --list-external-keys email@example.com
The same key is listed 10 times. (Which is also was Kleopatra shows in the
configuration as maximum search results)
Attached is the debug output.
