Taxonomy column on Media Library page is always empty.

[eddiemoya]

When a taxonomy is enabled for attachments in 3.5, a column for that taxonomy is automatically added to the table on the Media Library. However that column fails to ever populate with any of the terms assigned to the attachment.

[eddiemoya]

One-line fix, changes the "if" to an "elseif" as it should be.

Great catch.

It looks like this only breaks categories added to attachments, not any taxonomy. (As the second if/elseif/else would set $taxonomy to false, overriding $taxonomy = 'category'.)

[eddiemoya]

Correct nacin

For reference see how the same functionality work for the
​posts page.
