I have the same issue with Ubuntu Lucid and Evolution 2.28.3
When I go in the calendar, my exchange calendar is not displayed and I have to tick the box next to it.
After ticking it is synching the cal and after few seconds it crashes with a message saying "The Evolution calendars have quit unexpectedly" and clicking on that message gives the one above.

The syslog is giving:
kernel: [ 2203.955844] evolution-excha[2711]: segfault at 0 ip 046777a0 sp b5dfc128 error 4 in libc-2.11.1.so[4604000+153000]

And the gdb trace is:
