Subject: 23.2; debugger cursor getting misplaced
Date: Tue, 18 May 2010 09:42:02 +0100

New problem in Emacs 23.2 (at least on Windows).  When the debugger is
entered, the cursor is getting placed on random positions instead of the
first line of the backtrace.  For example, I placed debug-on-entry on
dired-get-subdir-min, and did dired-find-file.  The following backtrace
got generated, but the cursor was on the `call-interactively' line.
Doing subsequent 'd' and 'c' commands put the cursor on random
positions.

Cheers,
Uday Reddy

FWIW, I see this too (also on Windows).
