[Evolution] Memory leak in evo-data-server on Calendar Purge

[Bob Haddleton <bobh lucent com>]

Using Evolution 2.0.1 on Fedora Core 3 Test 3

I have a large calendar file and I wanted to Purge the old events to
improve performance.  I selected the Purge menu option and told it to
"Purge events older than" 365 days.

It starts processing the request, and as it runs the memory usage of
evolution-data-server grows by about 1MB per second.  Eventually it is
killed:

This is reproducible every time.

I'll take a look at the relevant code if someone can point me in the
right direction, or I can just file a bug.

Thanks
