189692 - When deleting a locale, don't remove the last locale for a component

Status: RESOLVED WORKSFORME

(Core :: Internationalization: Localization, defect)

Description

[Robert Kaiser]

In bug 189625, a user had a problem that he deleted the en-US locale from the
Language/Content pref panel after having the de-AT pack installed.
Now, there's no venkman translation in de-AT, but the reference to the en-US
venkman locale was deleted from the chrome registry as well, and therefore the
user got missing entity error when launching Mozilla.

The solution should be as following:
When deleting a locale pack, don't remove refrences to locale packs that only
have one installed language currently.

I don't believe there's a way, in current products, to remove the build language. If that's the case, it shouldn't be possible to reproduce this bug anymore. Feel free to reopen if there's still a current use case.
