[TYPO3-project-seminars] images getting removed from description

[Moritz Mack]

Hi!

I am failing to add images to a seminar's description in the rte and am 
a bit clueless what's going on.
Are there restrictions done on the rte's configuration?
Using the rte in other cases works well, thus it looks like a "locale" 
configuration issue.

Thanks a lot in advance and all the good work that is done here :)
