[rt-users] can't edit dashboards after upgrading to 4.0.13

[Robert McNicholas]

Hi,

A couple weeks after upgrading to 4.0.13 (from 4.0.7), I discovered that
whenever I click the "Content" link while editing a dashboard, I get the
error, "An internal RT error has occurred. Your administrator can find
more details in RT's log files."  In the log is recorded:

Jul 18 16:21:39 myhostname  RT: Can't call method "Content" on an
undefined value at /opt/rt4/share/html/Dashboards/Queries.html line
126.  Stack:   [/opt/rt4/share/html/Dashboards/Queries.html:126]  
[/opt/rt4/sbin/../lib/RT/Interface/Web.pm:635]  
[/opt/rt4/sbin/../lib/RT/Interface/Web.pm:335]  
[/opt/rt4/share/html/autohandler:53]
(/opt/rt4/sbin/../lib/RT/Interface/Web/Handler.pm:208)

This happens whether creating a new Dashboard or editing an existing
one.  We didn't notice the problem until a couple weeks after the
upgrade since the most used features of Dashboards work as expected
(viewing, sending emails), so I'm not 100% sure it is related to the
upgrade, but I can't think of anything else that might have caused this
to break.

I did some searching but didn't see any other similar reports.  Does
anyone have any suggestions on how to debug this further?  Thanks in
advance for any suggestions.
