Hi,

[17267534.120000] usb 1-3: USB disconnect, address 2
[17267534.120000] dvb-usb: bulk message failed: -22 (1/-909000848)
[17267534.124000] dvb-usb: WideView WT-220U PenType Receiver
(Typhoon/Freecom)
successfully deinitialized and disconnected.

Your DVB card is disconnected and that isn´t handled gracefully, DVB doesn´t
handle hotplug.
Then your mythbackend bites the dust. This happens when there is a disconnct
during use, the disconnect is the problem.

For someone to come with something useful, lsusb, kernelversion and hardware
information probably need to be included, but I´m no expert.

/Henrik
