Description

Originally reported by Chris Rebert (Bitbucket: cvrebert, GitHub: cvrebert)

If you ask coverage v3.6 to generate an XML report under a no-meaningful-tests edge case, it crashes:

<nose portion of call stack elided>
  File "/var/lib/jenkins/shiningpanda/jobs/f9dc77ce/virtualenvs/d41d8cd9/lib/python2.7/site-packages/coverage/control.py", line 647, in xml_report
    return reporter.report(morfs, outfile=outfile)
  File "/var/lib/jenkins/shiningpanda/jobs/f9dc77ce/virtualenvs/d41d8cd9/lib/python2.7/site-packages/coverage/xmlreport.py", line 88, in report
    return 100.0 * (lhits_tot + bhits_tot) / (lnum_tot + bnum_tot)
ZeroDivisionError: float division by zero
