changing component from one component1 to another component throws exception

[anonymous]

We had created a ticket that had used the default component1 component name.

We deleted that component1 name from the database using trac admin. Then we tried to switch that ticket to use the new component name. you can "preview" the change but not persit the change to the ticket.

Traceback (most recent call last):
