Another bug, related to this one:

If you click on the Create button in the Internal Error page that the ​Depgraph link opens, the following page opens: 

Request-URI Too Large

The requested URL's length exceeds the capacity limit for this server.
Apache/2.2.15 (Linux/SUSE) Server at dev.haiku-os.org Port 80

Which isn't all too surprising, as the URL is rather long:

It might be a good idea to change the submit method of the Create button from GET to POST.

The graph generation should now work.

The 'automatic' ticket generation is a Trac thing, I'll look at it when it is more problematic, but I reckon it is better to fix the issues :-)

Note: See TracTickets for help on using tickets.
