I filed a bug about an admittedly trivial issue about 6 years ago. Suddenly this summer there was a bunch of activity on it, somebody looked into it and made an effort to fix it. But that person was apparently new and didn't really know what to do, so I tried to handhold that person a bit. Then suddenly someone (that person's supervisor?) writes a comment implicitly chastising the person for spending time on a "low importance" bug. After that, the bug report went silent again.
Oh well, maybe someone else will fix it in another 6 years..
