          Priority: normal
            Bug ID: 4140
                CC: mercurial-devel at selenic.com
          Assignee: bugzilla at selenic.com
           Summary: Traceback occurs if no templates are available
          Severity: bug
    Classification: Unclassified
                OS: Linux
          Reporter: edmund.rhudy at yodle.com
          Hardware: PC
            Status: UNCONFIRMED
           Version: 2.8.1
         Component: Mercurial
           Product: Mercurial

This is kind of 1.5 bugs. When running hg log --style xxx (where xxx is a valid
template name), where no templates at all are actually available, you get back
an ugly traceback like the following:

** unknown exception encountered, please report by visiting

IndexError: list index out of range

(Incidentally, the reason there are no templates is because apparently
bdist_rpm does not correctly generate the file manifest on this platform
[CentOS 6.3] and pull in the mercurial/templates directory.)
