Adding a GPG key does not recognize all idents
Summary
Adding a GPG key does not recognize the idents asociated with the key.
Gitlab reads the key and does not produce any error message on production.log. On interface, key was added, and I can read my key fingerprint and the additional sub-keys fingerprint (The key have tree subkeys).
Problem are with email addresses. Only one email address are displayed on gitlab interface (and there isn't the mail email address).
I don't know the conditions to produce the bug. Ive checked it on gitlab.com webpage, on a debian installation from packages.gitlab.com package (version 11.5.1) and on a debian packaged non-omnibus installation (version 11.3.10, but tested also on 11.1.8 and 11.2.8).
I've tested with another key and there's added without problem.
I can do some tests for verify this bug, if it's required. My public GPG key are uploaded on public servers and added on gitlab.com if it's required for testing.
I remember, I've added the same key on a gitlab 10.x debian packaged non-omnibus installation, and then, I haven't detected this behavior. But, I cannot remember if I've changed something on the key after this. Also, I doesn't have any 10.x version for testing it now.
For more information, there's a bug opened on debian bugtracker. The issue address are: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914159
What is the current bug behavior?
Adding GPG key to profile, on some cases, does not recognize / does not show all email address asociated with it.
What is the expected correct behavior?
Adding GPG key should recognize all email address.
Relevant logs and/or screenshots
On logs there's not any interesting information. When adding GPG key, there's not errors on production.log
