It it not so much an incompatibility but a hard bug in ssh-keygen of my
own making :/
There is nothing we can do on the git side to fix this since the
find-principal call will always segfault no matter what.
I added an optional parameter some time ago for printing the public key
on verify to make "trust on first use" easier when we get to it.
Unfortunately this bug made it into 8.7 but is already fixed in master.
Thanks to Carlo for spotting it and sending a patch.
I guess i owe openssh writing a test for it since the command seems to
not have any at all.
I'm not sure how git wants to handle this since i don't know when a
fixed openssh release will be available and we certainly shouldn't
include the signing feature in a release until they do.
I can't really find a way of detecting the broken version since there's
no version or anything else i could find in the ssh-keygen tool.
I will continue writing some tests for the verify-time/key validity
feature. The tests will need some version/feature detection from
ssh-keygen as well so maybe i will still stumble on something that
allows us to detect and warn on this.
