Intermittent test failures

[Ryan J Ollos]

I've seen this a few times in Travis CI. It seems to be rather rare. Most recently it occurred on the trunk. I'm unsure as to whether the issue can occur on branches.

Reproduced. When wiki, header, logo or section is generated for tempfilename variable, the following link in logo is wrongly visited in the TestRepoBrowse test.

        <a id="logo" href="/wiki/TracIni#header_logo-section"><img src="/chrome/site/your_project_logo.png" alt="(please configure the [header_logo] section in trac.ini)" /></a>

It would be fixed by multiple random words.
