trac may not be able to handle svn properties named '.'

[OHKUBO.Takuya@…]

I put a SVN property named '.' on a directory by mistake (unfortunately my client 'svk' accepted such a odd request).

Since then, trac source-browser cannot display that directory. If I order trac to do so, it causes an internal error. Changeset browser does not work at that commitment, neither.

Python traceback is below:

Traceback (most recent call last):

I'll look into this.

Fixed in [2958]. This change fixes not only the pathological case reported here, but also handles correctly any property name containing a dot, like "a.b". Those property names are perfectly valid in SVN.
