[tsmr]

//$this->initForm(key($dbentries), $options); into function formDeleteEntry dans timeslotentry.class.php

correct the problem

Not have this error :/ Have you the scenario to reproduce this error?

I have this too on 9.1-1.1. To reproduce, create a timeslot and use as hours Monday 00:00 and Friday 24:00.
