I haven't used bulk actions much so I wanted to check my process before I submit a bug:

1:    Check multiple tickets via queue view, hit "Bulk".
2:    A visual confirmation appears:

2010103010000048: Ticket is used!

2010103010000057: Ticket is used!

2010103010000101: Ticket is used!


3: Perform a bulk update.

4: Check the three tickets. 

In my Beta 6 environment, only the first ticket has been updated.
