[TYPO3-seminars] CSV download doesn't seem to work properly

[Rolf Thiele]

Hi everyone,

first of all thanks a lot for the great new release. I just installed  
it and it's beautiful.

Still, I ran into a problem:
When using the csv button in the backend module  
"Events" ("Veranstaltungen" in German), Firefox downloads a php file  
and Safari displays the csv data within the TYPO3 backend.
plugin.tx_seminars.filenameForEventsCsv and  
plugin.tx_seminars.filenameForRegistrationsCsv seem to be ignored.

Any ideas what I could do?

TYPO3 4.2.12
seminars 0.9.0
oelib 0.7.0

Thanks,
Rolf
