You:

1) Appear to be the only one affected by it. 2) Don't have exact steps to reproduce it.

This makes it very difficult for anybody apart from you to work on the issue.

> nothing has been done about it.

From the bug, it looks like lots has been done about it.

> This worries me.

I think this is justified for you, but has little bearing on others. Software projects are full of bugs that only appear to affect one person. These bugs make little progress but don't necessarily reflect on the general quality of the software. Admittedly it is more of a concern on something like a filesystem, but I am still skeptical.
