gitweb error? - Mailing list pgsql-general

When I go to the following link:

http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=e6721c6e1617a0fc8b4bce8eacba8b5a381f1f21

I get the following error:

XML Parsing Error: undefined entity

Line Number 53, Column 4:

   ^

Is it just my browser being pedantic (Firefox 3.6) or something else?

Have a nice day,
