The issue with Irish has been further discussed at <http://askubuntu.com/q/685606>. An attempt to reinstall language-pack-ga-base resulted in:
Generating locales...
ga_IE.UTF-8... cannot open locale definition file `ga_IE': No such file or directory
failed
Hence the problem seems to be caused by an incomplete installation of the locales package. This is not a language-selector bug, so I'm closing this bug.
