[evolution-patches] patch for the bug #64398 [calendar]

[chenthill <pchenthill novell com>]

Hi,
  The crash in the getdeltas happened when the backend has died while
the E-D-S is still running. In this case cbgw is NULL and getDeltas
crashed. Have attached a patch to avoid the crash.

thanks, chenthill.
