Seems to happen fairly often on my Galaxy Nexus (Android 4.0.2), but can't reproduce on a Nexus One (Android 2.3.6).
When selecting a language from the "Read in..." menu, about half the time it's coming back with the next language in the list -- for instance selecting Turkish and getting Vietnamese.
May be a freak weird thing, or something odd about the events and scrolling or something.
Version: 1.0.0 (Android)
Severity: normal
