I think this problem is new (i.e., a regression). Perhaps it is not,
but I have not encountered/noticed it before.
Sometimes I cannot use the debugger at all (e.g., `debug' or
`debug-on-entry'), because the code being stepped through tests
(current-buffer) or (selected-window), and instead of the correct
buffer/window being tested, the buffer/window *Backtrace* is tested.
E.g., I tried `debug-on-entry quit-restore-window' and then hit `q' in
NEWS. The first thing `quit-restore-window' does is call
`window-normalize-window', which calls `selected-window', which returns
the window for *Backtrace* (e.g. #<window 40 on *Backtrace*>), making
all such debugging useless.

I checked in a fix for this in revision 110530.
