Fresh USB flash without settings restore, only set the language, activate network and tune channels.
If the setup item Setup -> User Interface -> Settings -> Sort setting screens alphabetically is set to Yes, the box crashes when trying to enter the menu Setup -> User Interface -> Subtitles
The weird thing is, this crash seems to only occur if the UI language is set to Finnish (Suomi). With English (US) no crash. Did not test other languages.
