MemoryError when requesting one specific change set

[richard@…]

How to Reproduce

While doing a GET operation on /changeset/73, Trac issued an internal error.

I receive an memory error when trying to view changeset 73 in my installation of trac. Other changesets can be viewed without problem.

Request parameters:

{'new': u'73'}

MemoryError

[cboos]

0.11b1 + Genshi 0.4.4 are known to be memory hungry (see #6614). This problem can manifest itself in MemoryError exceptions that can happen anywhere (possibly that changeset is bigger than your average changeset).

Some notable progresses have been made since then, and you should upgrade to (at least) 0.11rc1 or latest 0.11-stable, as well as upgrade Genshi to use its trunk version, ​Genshi:source:trunk@851 (you can do: easy_install http://svn.edgewall.org/repos/genshi/trunk).

If the problem persist with those versions, please reopen this ticket, giving as much details as you can on that changeset 73.
