Comment 1 MackSix 2013-04-17 20:43:00 UTC 
The cause of this is adding comment markers "<!-- -->" around the <properties> tags. I guess it is not really a bug, although it should handle the case where there is no <properites> tag more gracefully. Lowering to P4.
Comment 2 Martin Balin 2016-07-07 08:52:36 UTC 
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
