2.0: Pristine packages not getting extracted as they should

With 2.0 and build 2111 when I delete all packages from the %APPDATA%\Sublime Text 2\Packages directory (except User) I expect ST2 to, like in previous builds, repopulate the Packages directory from the Pristine Packages directory. This goes wrong now, I get:

"Error loading syntax file "Packages/Text/Plain text.tmLanguage": Error parsing plist xml: Failed to open file In file "Packages/Text/Plain text.tmLanguage"

And nothing in Packages gets repopulated from Pristine Packages. Even if you extract the contents from Text.sublime-package to Packages\Text ST2 does not extract the rest of the Pristine Packages to Packages. A major regression from previous versions/builds.

If you remove both Packages and Pristine Packages and start ST2 it does populate Pristine Packages and then Packages.
