This is a raspberry pi 3.
I am in the default theme terra, and the first example is going from the the settings to
the theme chooser menu. The display stays with theme chooser, and doesn’t move to the list
of themes available.
Interestingly, the cursor re-appears, and I can’t give focus back to  mythfrontend. 
I can do an alt tab to see the terminal screen i started mythfrontend from.

I see a DB error 2/2027,  Unable to execute SQL statement. Database error was malformed packet.

The query it blames is
select grpid, name from channelgroupnames order by name.

There appears to still be activity from mythfrontend as I see CEC adapter warnings continue to scroll.

Control C twice will kill mythfrontend in the terminal session.

I am using the latest raspbian apt updated, rpi-updated, and installed latest mythtv-lite from your repo.

No hard drives attached, and I am using a keyboard only.

Thanks for the assistance!
