Hopefully not any more. Did you try the latest trunk?

We can now kill the *Completions* buffer as well. We only have to be
sure what's easier - keeping track of `other-window-scroll-buffer' and
resetting it or killing the buffer. Somewhere there should be a
`quit-restore-window' call around, responsible for accomplishing part of
that task already.

Then try fixing that. At the time of displaying the *Completions*
buffer set `other-window-scroll-buffer' to the *Completions* buffer. At
the time of removing that window (I hope it gets removed) reset
`other-window-scroll-buffer' to nil or kill the *Completions* buffer.
Writing this should be simple once you know where to apply the changes.
The more important task is to give it some testing.
