This really needs to be reported/fixed upstream. https://www.gnupg.org/documentation/bts.html We can backport a fix once that has been done.

Thanks!
fixed in their master for 1.10 https://dev.gnupg.org/T6432 https://dev.gnupg.org/rC7edf1abb9a0d892a80cbf7ab42f64b2720671ee9
> fixed in their master for 1.10 i mean their master not 1.10
