Summary: NullPointerException in 'Lines of Code' chart generation

Initial Comment:
When I want to use StatSVN on our project there occured the following error:
Parsing SVN log './logfile.log'
Scheduled 0 svn diff calls on 0 threads.
Generating report for /trunk into ../neco/
Using default CSS file (statcvs.css)
writing chart 'Lines of Code and Churn Level' to locandchurn.png
Creating CSS file at '../neco/statcvs.css'
writing chart 'Activity by Hour of Day' to activity_time.png
writing chart 'Activity by Day of Week' to activity_day.png
writing chart 'Commit Activity' to commitscatterauthors.png
writing chart 'Author Activity' to activity.png
writing chart 'Lines of Code' to loc.png
Exception in thread "main" java.lang.NullPointerException

        at net.sf.statsvn.Main.generate(Main.java:112)
        at net.sf.statsvn.Main.main(Main.java:83)

I know that project is "non-standard" but probably error shouldn't occur.

Hi

I believe that the issue is in StatCVS. I will raise it with the
development team.
Have you added files since having faced your issue?  Would you mind
retrying?

TimeLineChartMaker toFile returns null when timeLine.isEmpty(). Which
would be on first check in I guess.
but then Page.add(...chart) will simply assume that chart is never null.

Hope this helps
Benoit

When you run a statsvn with the "-dump" what do you get?
Could you record that output and post it here?
Thanks
Benoit
