Several Template Hierarchy areas a broken

[thee17]

I think I found a problem in trunk. If you category-term.php in a there does not work, category.php does, I have tested author, taxonomy, and tag with similar results. I was able to duplicate on 2 sites running the most recent trunk. I think the problem is in [15611]. When I revert the wp-includes/theme.php back to revision 15610 it works as expected.

Could you post more detailed steps to reproduce?

Take a category, tax, or tag:
(using categories because it is more likely you have one to test. For this example the catagory ID is 5 and slug is test)
Create a category.php to your theme visit your category test and the template is your category template.
Rename it to category-5.php or category-test.php and the visit your category and you will see it use your archive.php or index.php rather than your template.

mrmist was also able to reproduce in #wordpress IRC today.

get_query_var( 'cat' ) returns a blank string on the category archives page.

Utkarsh, that's a different issue. Please report it on #12891

Ah, I see what you mean. Related, anyway.

(In [16115]) Use get_queried_object() in more get_*_template() functions. Fixes #15263
