= Description =

When I search any term (in titles or in text) without hits, I get an error in my '''spanish-configured''' browser.

I get this page:

{{{
ValueError

unsupported format character 'C' (0x43) at index 121

If you want to report a bug, please save this page and attach it to your bug report.

    * Show debugging information
    * Report bug
    * Visit MoinMoin wiki
}}}

Python shows on console:

{{{

I can't reproduce this. Can you try it again and give more details?

True! I'm using the '''spanish''' language configured in my browser. Using english goes ok. This happens with the spanish page. It seems to be a problem with the translated message (some incorrect character, maybe?). Try now changing the default language of your browser preferences to spanish.

OK, I could reproduce it. But I am still working on finding the reason for that strange behaviour...

The language to check is Espanol :)


The reason for that bug is that we dont escape % chars in result of substituting text. e.g. always if a wikiname is substituted to its url it has escape chars for the url address. Those chars start with a % sign. Because the next char following this % sign is not defined as subsitution char we got this error. 

We have on file attachment view a similiar problem: e.g. [[http://test17.wikiwikiweb.de/ReimarBauer?action=AttachFile&do=view&target=abc.png|view]]


if we change in AttachFile.viewFile formatted to False as a workaround the problem is gone
{{{
title = _('attachment:%(filename)s of %(pagename)s', formatted=False) % {
        'filename': filename, 'pagename': pagename}
}}}
