Suddenly my n900 is displaying technical strings instead of actual titles, like "wdgt_va_24h_time" instead of the clock, and "mp_ap_name" instead of "media player" (in the menu)

Also, when trying to access regional and language settings, i get this error message

"memr_ni_application_closed_no_resources"

seems like i have the same problem as here, but i have no idea how to solve it.
