I have a different issue, I think it has something to do with male/female relations at workplace. I'm the lead dev in a mixed team. And one of devs, who happens to be a girl, has some special attitude. Whenever I report a problem with the code, or a bug, she jumps in and exclaims it's not her code or she didn't do anything related to the problem, basically not her fault [without any suggestions that it might be her fault]. Sometimes tries to blame someone else. If anything points to her responsibility, she downplays it (oh you know I don't even remember). All while I try to avoid blaming or pointing code ownership. But the most difficult part was when I pointed out some parts were missing in her work and function wasn't completed - then I was accused of being mean and attacking her without any reason. Never had such situation, I am rather a considerate, polite person, try to remain professional and never touch personal side - but this just perplexed me. With a male dev it would not be possible, but when a woman accuses a man of harassment or bullying at work the man is considered guilty by default. I perceived this as a threat - never ever criticize my work or you will be accused. Unfortunately she's not doing that great job sometimes and so cooperation gets quite difficult - and I'm afraid it's not going to be good in future.
