Saving channel information on mythweb causes fatal error

[o.juhl@…]

I saved channel information on mythweb in order to delete 2 channels, when an webpage came up with a error message. The below tekst is a part of that page. It is a new installed mythbuntu 16.4 using a dvb-t usb tuner.

Dup of #12811.
