Hi Torsten, I ran into this last week (RT 3.4.5), and wasn't able to find much on Google or the list archives about it. It does seem to come up when people are trying to do different things.
In our situation, it was the result of the following:
1) Two tickets were created for the same issue (customer double-submitted it)
2) A link was created between them ("Depends on/Depended on by")
3) The link was removed
4) One was deleted, and subsequently purged from the database with RTx::Shredder
With the database in this state, trying to load the ticket that hadn't been
deleted resulted in the error you describe. My solution was to restore the
deleted ticket using the dumpfile created by rtx-shredder's --sqldump switch,
and set its status to "rejected" so that it isn't automatically purged by our
nightly rtx-shredder job.
I'm not sure if we could've done anything else (removed the link transaction(s)
from the database perhaps? I didn't try this because I'd rather add unnecessary
data than delete anything), or if this is a bug or an unavoidable consequence
of using RTx::Shredder to purge our database of spam (there is plenty). The
bottom line, for us, was that the two tickets should've been merged, as they
were both from a legitimate customer. Deleting one was the incorrect solution.
Sincerely,
Frank Pater
