11139	"rescheduleTickets  OperationalError: near "","": syntax error"	Oscar Andreasson	Chris Nelson	"Originally posted the issue in #11105 comment 10 http://trac-hacks.org/ticket/11105#comment:10 but realized this may be a separate issue. 

This happens when I change for example blockedby and blocking custom fields. I have several fields that may contain trash data due to bad user input and no sanitation of user input in case this is of any help. 

Disabling the ticketRescheduler component of the plugin fixes the error message, but I'm guessing there should be a permanent fix as well as this causing some kind of issues...? A part of the dump below:

----
Oops…
Trac detected an internal error:

OperationalError: near "","": syntax error

This is probably a local installation issue.
Found a bug in Trac?

If you think this should work and you can reproduce the problem, you should consider creating a bug report.

Note that the Trac-jsGantt plugin seems to be involved. Please report this issue to the plugin maintainer.

Before you do that, though, please first try searching for similar issues, as it is quite likely that this problem has been reported before. For questions about installation and configuration of Trac or its plugins, please try the mailing list instead of creating a ticket.

Otherwise, please a new bug report describing the problem and explain how to reproduce it.
