What version are you running?

1.6RC2

We frequently receive the following traceback. I don't know how to reproduce, since that's sent by mail, so I don't know what the user was doing when the error was catched.



Traceback (most recent call last):

Encountered this same error today

#3 chipx86 
This is indicating that it's unable to find the template file for the cell. Did you restart your wsgi process/web server since upgrading? And how long has this been happening?

I'm doing a Djblets release tonight. I can add logging when this fails, but I don't believe there's really a problem to fix per se. This looks like an installation issue.
#4 degrand********@gmai***** (Google Code) (Is this you? Claim this profile.) 
Yes, the server was restarted.

We were before using 1.5.5 with mod_python and sqlite.

I transferred the database on a new server (with RB 1.5.5), using postgresql. I used django dump/load for the transfer, and then updated to 1.6RC2. I got that bug since then.

If it's a template file missing, how can I find which one ?

I haven't seen this error in quite some time with 1.6.x releases.

#6 thom.******@gmai***** (Google Code) (Is this you? Claim this profile.) 
I still see this issue sporadically: approximately once a day out of aprox 3000 GET requests to /dashboard/ with Python 2.6.6, Django 1.3.1, ReviewBoard==1.6.6, Djblets==0.6.16.

The logging chip added never ends up in the log files, which is baffling because I don't see any way the code would get to the render call without the logging being triggered.
#8 Chris******@actia***** (Google Code) (Is this you? Claim this profile.) 
I'm seeing this with the RB version 1.6.11, a few times a week. Appears to be the same as issue 2720.
