[Buildbot-devel] UnicodeDecodeError in webfrontend

[Christoph Spielmann]

Hi,

I tried to apply your fix (i don't know if this was the correct place 
but from my understanding this should go to status/web/base.py) but to 
no avail, i still get the same error:

2013-03-04 11:02:09+0100 [HTTPChannel,11,192.168.2.166] Unhandled Error

         exceptions.UnicodeDecodeError: 'ascii' codec can't decode byte 
0xe4 in position 7: ordinal not in range(128)

Furthermore i remarked yesterday that jinja needs Babel for i18n-stuff 
so i checked if that is missing and it actually was but this was another 
dead end...

If i restart the buildmaster and look at the footer of the pages i see this:

BuildBot (0.8.7p1) working for the Machineering project.
Page built: Mon 04 Mar 2013 11:45:47 (CET)

And this is what really makes me wonder what is going on that suddenly 
somehow a 'ä' is appearing in the date. If there would be a general 
problem in the way the date is rendered, shouldn't it pop up as soon 
jinja is trying to render the page? Especially for the first time?

Thanks again for your help,

Christoph
