Bug Description

When attempting to save a modified event (update a meeting date and time to tomorrow), evolution returns:
»Cannot modify calendar object: Unexpected HTTP status code 412 returned
(Existing event has different ETag)«

This also occurs when trying to update attendee status after receiving a confirmation by email.

I am using current 3.2.3-0ubuntu4 on 12.04 Beta.

The upstream patch is a workaround for a bug in libical48, which apparently has an escape character issue, as described upstream but patched in evolution to workaround.

I tested the patch, re-attached here against current 3.2.3 sources, and it is simple and applies cleanly and resolves this problem completely.

upstream: https://bugzilla.gnome.org/show_bug.cgi?id=669003

Steps to Reproduce:
1. Configure Online-Accounts OR add a Google Calendar manually
2. Open Calendar, enter password
3. Try to change or delete existing event
4. Get error message: Cannot modify calendar object: Unexpected HTTP status
code 412 returned (Existing event has different ETag)

Actual results:
Not able to manage already existing events.

Expected results:
Should be able to manage already existing events.

Any reason this patch hasn't made its way into current 12.04 Beta? I have been using it for quite some time and want to avoid setting selections manually.

It is a simple, straightforward fix, for a 100% repeatable issue that has been triaged and patched upstream.

Along with recently released https://bugs.launchpad.net/evolution-data-server/+bug/847578, this makes Google calendar work again (been broken since Natty).
