Same here. For me, it happened the first time I tried to remove something from the "blocked by"/"blocking" fields.

My main problem is that even after I removed all values from the "blocked by" and "blocking" fields from the related tickets, the depgraph is still the same. The content of the graph and the content of the ticket remained inconsistent, even after I restarted Trac.

Occurs here too after removing "Blocking" tickets.

Note that the blocking tickets I had added were already closed (it might help..).

I get the same error when I try to change a ticket from "blocked by" to "blocking."
