Since 1.1.2 we get multiple entries in AgendaList if an event has more than one category selected. The number of entries for an event matches the number of selected categories. This only happens if we list all events without any filtering.
This could be a bug, since the Query for the events was changed, to get the event count right for the pagination. Could you send me a db dump of your events?
1.1.2-pl2 containing the fix will be available today. Sorry for the issue.
Wow, that was quick! Thanks! Do you still need the db dump?
