crash if svn directory contains uncommited 'svn cp'

[Tomasz Bury <tomek bury gmail com>]

Hello,

Meld crashes when I try do display svn working directory containing
copied files. The bug is easy to reproduce using meld 1.5.x or trunk
and stock svn from Ubuntu 10.10 (svn, version 1.6.12 (r955767)). Check
out anything from subversion and run 'svn cp existing file new-file &&
meld .'

The patch that fixes this problem is attached.

Regards,
Tomek

Subject: [PATCH] Fix crash when displaying svn directory containing uncommited copies

There's no revision information in such case, just 'copy': True.

To reproduce the problem sun 'svn cp existing-file new-copy; meld .'
