User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.6) Gecko/2009020409 Iceweasel/3.0.6 (Debian-3.0.6-1)
Build Identifier: Version 0.9

The goal:
A reminder shall be created at the last Wednesday of the month.

The setup:
Zimbra is used as caldav backend.

Using Sunbird:
While creating the event in Sunbird, the event shows up at the desired position. Both applications work correctly. The generated rule looks like this:
RRULE:FREQ=MONTHLY;INTERVAL=1;BYDAY=-1WE

Using the Zimbra webinterface:
The event shows up at the right position within the webinterface. Sunbird however makes it show up at _every_ Wednesday. The generated rule looks like this:
RRULE:FREQ=MONTHLY;INTERVAL=1;BYDAY=WE;BYSETPOS=-1

Reproducible: Always

Steps to Reproduce:
1. Create a new event at the last Wednesday of the month within the Zimbra webinterface.

Actual Results:  
The event shows up every Wednesday while using Mozilla Sunbird.

Expected Results:  
The event shall appear at the last Wednesday of the month.
