'compile-goto-error' results in the

    "pop-to-buffer: Wrong type argument: window-live-p, nil"

error if appropriate file is not loaded or loaded, but appropriate
buffer is not visible in the same frame where '*compilation*' buffer
lies.

Sources obtained from CVS today, Fri, 16 Jan 2009 12:50 (GMT), but
first time reproduced with yesterday's checkout.  Previous checkout
was far ago in paste (and definitelly in the 2008 year), therefore, I
unable to say exact time of the problematic commit :-(

In between here is the call to `display-buffer' which for some reason
returns nil in your case.  Could you try to edebug `display-buffer'
(from another frame to not break the window layout) and tell me from
which line it returns nil?

Thanks, martin.

Sorry, it was my fault.  I inadvertently comitted some experimental code
when reverting an earlier change.  Please try again with latest sources.

Thanks for reporting, martin.
