[evolution-patches] fix for the bug #322951 [calendar]

[chen <pchenthill novell com>]

Hi,
  Have attached the fix for the bug. I could not reproduce the scenario
mentioned in the report. It could be a threading issue, have put a mutex
lock to avoid the reinitialization of the type value.

thanks, Chenthill.
