I've stumbled across an inconstancy in the display of who deleted an answer.
In How to rate your programming skills on Programmers.SE there are currently two deleted answers.
The display of these two questions - one has the name of the owner, the poster, the other has the string "deleted by owner".
The differences that I can see are:
- that one is a 10k+ user and the other is not and maybe the code for how it handles deletes of answers for these two is different.
- the dates are about a day apart, there might be different versions of the software (yet, its still rather short of a timeframe)
So... it just looks like a minor cosmetic bug that most never see, though may be hinting at duplicated code that could lead to a different bug some time down the road. Or it could just be that two different releases of SE software put two different strings in the delete message and thats it, never mind, and everything is working as intended.
Of note, there was some tinkering of the self deleted code and display name back on July 17th - Self-deleted posts by deleted users don't show “deleted by owner”. This isn't the discrepancy seen (neither of these are deleted users), but it might help those with access to the code to look in the area of the code.
