Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

For some reason I redefine a short-cut key for "Mark set".
What I do is add the following line in ~/.emacs:

(global-set-key [(control x)(w)] 'set-mark-command)

I find this works well under some nomal edit conditions except in the
Calendar mode. In the Calender mode, when I type in "C-x w", the
mini-buffer also show "Mark set", however it actually not work at
all. Only the "C-space" can do the really "Mark set" job.
