The original log also included:
which might be an issue?< 413.3938> [Skin] Warning: Skin screen 'SkinSelector' rejected as it does not offer all the mandatory widgets 'skins, preview'!
< 413.3939> [Skin] No skin to read or screen to display.
(Unrelated: and that log also included a long traceback dump from, probably, some transcoding code.
Looks like someone left some debug code in place in production code?).
