upgrade to v3.3.2 caused internal-linking.php missing error

Hi there,

after upgrading to wordpress v3.3.2 the dashboard would give me an error message at the bottom of the page telling me that the file “/wp-admin/includes/internal-linking.php” is missing causing an fatal error in the “/wp-admin/admin-functions.php”.

my website was showing all content loaders eternally pre-loading as well as a standart font instead of the installed cufon font.

I copied the file “internal-linking.php” from my backup into the required destination and my wordpress dashboard worked fine, showing up the new features guides. no more error messages.

but still, the content loaders won’t find their contents and the cufon font is not active.

– the database was not affected
– the media that should be loaded is still in the uploaded locations
– the font is activated in the admin panel (r-panel)

can you help me find a solution, please?
