Here's the debug output for the relevant time period. Nothing interesting that I see.
The first set of KEY_LEFT events is navigating back from "System" to "TV".
At 12:19:44 the system is idling with TV highlighted in the Home menu (cpu usage is pegged).
After 15 seconds (at 12:20:00) I navigate to Music (cpu usage drops). [The KEY_RIGHT events]

The only thing in the log is:

Code:

12:19:44 T:2960786448   DEBUG: NEWADDON PythonCallbackHandler construction with PyThreadState 0x1eb1368
12:20:00 T:3035631616   DEBUG: Previous line repeats 32 times.

After a few seconds I navigated back to TV [The KEY_LEFT events].
The final set of KEY_RIGHT events is navigating back to the system menu to turn off debugging.

Edit:
Moved debug output to paste.bin:
