Does the remote machine have the proprietary nVidia drivers installed?
I *think* what's happening is that when programs are run on the remote
machine it sees that there are various GL extensions available, tries
to use them, and fails because they don't exist on the local machine
where the GL requests are actually performed.

As for fixing it - I think doing 

  export LIBGL_ALWAYS_INDIRECT=1

before running evolution from the command line might help - it
certainly does for other GLX issues.
