Bug 332594

Description Michael Kopinsky 2010-12-14 19:33:23 EST

What steps will reproduce the problem?

Using a PHP file tracked in Mercurial, right click the file -> Compare with -> Parent Changeset. I can't say this occurs for all PHP files tracked in Mercurial, but it does happen repeatedly for this file. If necessary, I will provide a mercurial URL so you can check out and reproduce.
