[TYPO3-project-seminars] onetimeaccount does not work in TYPO3 4.2.5 anymore

[Alexander Grein]

Hi Oliver,

after updating my TYPO3 from 4.2.3 to 4.2.5 the onetimeaccount-Extension 
seems not to work correctly anymore.
After select a seminar i will be redirected to the onetimeform like 
before. But after filling in the form, i always get the screen "you are 
not logged in".

After switching back to 4.2.3, everything (beside the TYPO3 security 
fixes!) is fine again.

Greeting

Alex
