It is certainly the case that Galaxy should be using the latest
version of mercurial given a number of high profile bugs with older
versions. Unfortunately it doesn't seem possible to just drop the new
version it - there are some API changes that prevent Galaxy from
loading when doing this and the number of people who can add new eggs
to Galaxy is low.

I have created a Trello card to track this issue:

Let us know if you happen to find a workaround for this issue.
