In interactive mode, "list" command stops working correctly after some errors

After certain errors, the "list" command stops listing all commits in the selection, and only lists the first if the first event is a commit, lists nothing if not. Example:

$ cd ~/reposurgeon/test
$ reposurgeon
reposurgeon% read <simple.fi
131 events (53K/s)
* simple
reposurgeon% list
