I assume that you have `pop-up-frames' = t or something similar - something that
causes buffer *Completions* to appear in its own frame.

In vanilla Emacs, `C-g' does nothing to remove this frame, as you say.
Icicles does not have this problem:

In Icicles, if *Completions* is displayed in its own frame (sole window), and
that frame has no minibuffer or has only an inactive minibuffer, then the frame
is deleted when you use `C-g' (or when you choose a completion candidate).

Perhaps Toby Cubitt (author of Predictive) can help with that.
