As Vesa is pointing out, the rule for quality software should be:

1)  Add the regression test case to detect the problem.
2)  Run the test (to make sure the bug really is detected.)
3)  Fix the bug.
4)  Run the test (to make sure the bug really got fixed.)

It is a bit laborious for simple bugs; but it really pays huge dividends 
over the long run.

Thanks for mentioning it.
