Yep.

I'll probably have a look at this as well as other
languagechooser/countrychooser bugs in the upcoming weeks.

This is probably a consequence of the default locale for Spanish being
set to es_ES@euro and wrong code in languagechooser or countrychooser
when it comes at keeping the modifier part of the initial locale.

All this is a bit tricky as we don't really have code for setting up
the modifier part of the locale except what we have as a default in
languagechooser.

Joey's workaround is a good idea anyway which can even be kept when
the real bug will have been fixed.
