Regression tests.

[Amar Takhar]

Does anyone have any suggestions for commits that should have regression tests?  
Typically we'd do this off of a bug report so what I will do is open a ticket 
first then write a test for it.

Not all suggestions will be suitable I want to have these as examples for anyone 
wanting to write a regression test.

There is a new ticket tag, NEEDS_TEST for any bugs that need a regression test 
before closing.
