Taxonomy legend colors are not applying. [#1388364]

I'm aware of the closed issue #1161632: Taxonomy legend colors are not applying. but there are no further instructions for helping with my issue.

Test case using following modules:

Calendar 7.x-3.x-dev from 2011-Dec-29
Date 7.x-2.x-dev from 2011-Dec-29

I've already done all the troubleshooting steps mentoined in the article "Debugging date and calendar problems" (http://drupal.org/node/755312).

Steps to repeat:
1. Edit the default view of calendar.
2. Delete all sites and blocks within the view except the month view.
3. Add taxonomy term from content type to fields.
4. Set the output to be a link, not plain text.
5. Click on Settings in the Format Show section and select the vocabulary to set the stripes based on. Click Apply.
6. Once again in the settings, select a color for each term of the vocabulary.

The expected result should be, that the calendar entries are marked with the colors based on taxonomy terms, but they aren't.

See attached a screenshot of the view settings which are important and to make sure that I've set all right.

By way of comparison the legend colors based on content types are displayed correctly.

Any hints?
