Thanks for following up, but that sounds kind of unrelated to this bug.
If you aren't seeing a message starting with "Error informing the kernel
about modifications", it isn't this.

"Still mounted" messages aren't necessarily bugs. There's a UI there to
cover it because it's a legitimate case; and I can't currently think of
a reason they'd be particularly connected to this bug, although I
suppose it's possible that they're a consequence of continuing past the
error messages somehow.
