The `.emacs' you attached still loads tons of
stuff, and performs various configurations.

Try starting Emacs with `emacs -Q' (no init
file), and then just loading file `dired+.el'.
Do `M-: (setq debug-on-error t)'.

If the bug is present in that case, then
please report it to me directly, with the
backtrace.

If that's not enough to repro the bug, add
one or more of your Dired configurations, to
see if the error arises.  The less you change
the better, for debugging.
