unicode decode error when accessing timeline

[greer@…]

i have a fresh install of trac, everything seems to be working except when i access the timeline for my project.

Trac detected an internal error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 64: ordinal not in range(128)

File "/usr/lib/python2.5/site-packages/trac/timeline/templates/timeline.html", line 46, in <Expression u"event.render('description', context)">

Which version control backend are you using?

i am not exactly sure i understand the question. where do i find this information. i am using trac 0.11, running on mysql 5.0.67-0ubuntu6 on top of ubuntu 8.10

I meant, is the repository you're browsing a Subversion repository, a Mercurial or git one… But I guess you've answered, it's most certainly Subversion, as for the others you would have to install a dedicated plugin ;-)

Just to be sure: do you have any other plugin installed, in particular one that could interfere with the wiki formatting? If so, try disabling plugins one by one, to identify which is the problematic one, if any.

Then please try to go to the individual changesets (starting by /changeset/head, then going back), identify which one can't be displayed. Then on the command line, do svn log -r XXX -v --xml (XXX being the problematic changeset number), and post the result.

I found the culprit, it does have non-ascii characters in it.

Okay, this is nevertheless strange, as we normally take care of converting Subversion commit messages to unicode.

Is this repository public?

[greer@…]

Unfortunately, we cannot make the repository public at this time.

[Christian Boos]

Well, I can't reproduce the issue when using the commit message from comment:4. As expected, this gets properly converted to unicode.

Which version of Trac are you using exactly? Not a patched one? (there exist some unofficial "i18n" versions of 0.11).

As I can't reproduce the issue, this is something you'll going to have to debug on your own. If you find out this is indeed a problem in Trac and you've come up with a fix (or at the very least a clear indication about where Trac is misbehaving), then please reopen.
