[evolution-patches] Patch that Fixes bug#74218 (evolution-exchange)

["Jain Vivek" <jvivek novell com>]

Hi,

The attached patch fixes
http://bugzilla.ximian.com/show_bug.cgi?id=74218

changes are made in calendar/e-cal-backend-exchange-calendar.c 
There was a crash, as the string that was not allocated, gets freed
later on.
I am allocating the string before its assigned.

Thanks,
Vivek Jain
