Used to describe a final/minor step or issue in a computer/software repair that becomes in itself a major issue.

A 'columbo' is named for a the TV show detetective by the same name who was known for his phrase at the supposed end of his questions/investigation "oh yeah, one more thing" - and USUALLY that 'one more thing' is the 'kicker' as it were.

That airbook setup had more columbos than I could count!
