Genshi UnicodeEncodeError error while rendering template

[daniel.velez@…]

I get a Genshi UnicodeEncodeError while click on timeline in one of our projects, I checked previous ticket about this bug but nobody mentioned the issue clicking timeline.

I enabled use_chunked_encoding = true, but it didn't work.

[Jun Omae]

A possible duplicate of #12490.

Typically, the UnicodeEncodeError is caused by installed plugins. Please post system information from about page of your Trac and stack trace of the error in your $ENV/log/trac.log after use_chunked_encoding = true and reproducing the issue.

Hi there, after use_chunked_encoding = true.

I attached a file with system information

got:

[anonymous]

we are having the same issue in the ticket /ticket/5374 too

[anonymous]

Your Trac is too old (Trac 1.0). Please try Trac 1.0.19.

[anonymous]

Can you give the instructions for that upgrade?

I found only instructions to upgrade from 1.0 to 1.2

https://trac.edgewall.org/wiki/1.3/TracUpgrade#to1.2

thanks!

[Ryan J Ollos]

Steps are listed here: 1.0/TracUpgrade.

Suggest replacing easy_install --upgrade Trac==1.0 with:

$ pip uninstall trac
$ pip install trac==1.0.18

You may not have pip installed since you are on Python 2.6.x. ​Here are instructions for installing pip.

If you still have the error after your upgrade, disable all plugins. Presumably the issue will be fixed, then enable them one at a time until the issue is seen.

[Ryan J Ollos]

We will reopen if it's not an InstallationIssue, but that's unlikely. Feel free to follow-up here or on the MailingList if you have more information to share.

Hi Ryan J Ollos

The upgrade worked well, thanks for your recommendations, we appreciated it.
