The language selected is grayed out after updating the latest packages. Clicking on the language wanted generates this bug.

I would think that this bug happens once you start Language Support, but that the dialog that tells you about it appears only a few seconds later. If you start gnome-language-selector from a terminal window, you'll probably come to the same conclusion.

For me it happened after I opened the Language Support dialog from the system settings window.

Yes, you don't need to do anything else. That's what I meant too.

Anyway, this bug will go away with the next language-selector version.

Thank you (I don't know that anyone will write to me). After computer
restart My language was installed, so this bug probably is not so serious.

This bug was fixed in the package language-selector - 0.54

language-selector (0.54) oneiric; urgency=low

  * data/LanguageSelector.ui:
    - Reference to the handler "on_treeview_languages_cursor_changed",
      which was removed in v. 0.53, dropped (LP: #859961).
    - Property "relief" for help button reinserted.
  * LanguageSelector/ [change not affecting KDE]:
    - Don't confuse the UI by testing whether dropped metapackages
      are installed. Makes a difference on upgraded systems where
      (traces of) such packages are left on disk from previous
      language installations (should affect LP: #841712).
