The following HTML does not seem to properly round-trip through VE:
<p><a rel="mw:WikiLink" href="././Foo">./Foo</a></p>
While the ././ prefix is not ideal (see Parsoid bug 50426) VE should still preserve the href on unmodified content. Instead, it seems to prefix another ./, which then results in diffs like this one:
Version: unspecified
Severity: normal
Those prefixes actually seem to have been inserted by VE:

This seems to also seem to replace spaces with underscores, and mangles category links. EG changing [[Category:House (season 7) episodes]] to [[./Category:House_(season_7)_episodes]]

It worked at http://en.wikipedia.org/wiki/User:Catrope/Shrek?veaction=edit though, so closing as working.
WORKSFORME is not good enough for a resolution for this bug. This seems to be quite a rare bug which I've only seen in edits with the visualeditor-needcheck tag

Looking thorough that this edit
https://en.wikipedia.org/w/index.php?title=Ron_Davies_(songwriter)&curid=31118393&diff=562723238&oldid=553701771
introduced the bad markup and that was only a couple of hours ago.
Note that I also deployed a fix for bug 50426 just before I closed this bug. That will avoid triggering this in VE even if there is still a bug.
My problem is still occurring. I've now created bug 50720 for the specific issue I'm seeing. The latest occurrence was 05:07, 4 July 2013
