Found root cause. That is a Trac issue.
This issue raises if permission group name is used in owner, reporter or
updater of a ticket when the ticket is updated.
Workaround is to rename the permission group name to something that is not used
as a reporter or owner of tickets or username (e.g. "admin" -> "%admin").
The exception will go away by the following patch, however notifications to the
users will no longer fire when the permission group is used in reporter, owner
or updater of the ticket.
