Testing the 1.4 CVS version (new installations and update installations) I found
that the Interface Language in User Preferences was set (defaulted) to Africaans.
In my humble opinion fresh MediaWiki installations should come with a
"(uninstalled yet - please choose)" default interface language, proposed: English
OR, better:
the interface language should be set automatically to the installation (content)
language.
Version: 1.4.x
Severity: normal
