Keepkey Domain register AssertionError: None

[marek22k]

Hello, I am using the wallet with my KeepKey. The KeepKey is up to date. I set it up normally and transferred a small amount to Namecoin. Next I tried to register a name.
What was a little strange is that I was asked for a password (not the password for the KeepKey) because I never set one. I then just clicked "OK". The relevant data was entered and then it appeared that an error had occurred (see below).

Is that up to me? Is that a bug in the program?
I hope it's okay that I made a new issue here.

Hi! Thanks for the bug report. Name operations are not yet supported for hardware wallets. This is due to missing support for name operations in the firmware. We intend to submit firmware patches to KeepKey, but haven't had a chance to do it yet.
