Personal time lost to fixing problems can always be annoying. However, not all debugging situations are like that.
There is something terribly satisfying about digging into a problem on a production system that rears its ugly head once a month (requiring a system to be rebooted), brainstorming, setting up test scenarios, getting the bug reproduced, finding the source of the problem, fixing it, testing it and seeing that it has been nailed! (oh, and equally satisfying is seeing the days of uptime on said machine thereafter measured in 3 digit numbers :-D)
And the problem I have in mind was someone elses code. I still enjoyed every minute of the debugging process.
