I suppose you meant `other-frame' here (next-frame is a C
function) and in the title.

I again suppose you mean `other-frame' here, otherwise I would say it's
not a bug, since the the *Backtrace* frame does exist by the time
`next-frame' is called.
By the way, from your backtrace it looks like you did debug-on-entry on
`other-frame', but in that case there's no way for it to "snapshot" the
list of existing frames "before" the call, since you've stopped in the
debugger before any of its code is executed. It's only possible to fix
the case where you stop only later on next-frame.
