     Type:  defect         |     Status:  new
 Priority:  Low            |  Milestone:
Component:  buildbot/mpbb  |    Version:
 Keywords:                 |       Port:
---------------------------+---------------------
 Example:
 https://build.macports.org/builders/ports-10.8_x86_64-watcher/builds/1620

 Notice `[property`, `value`, `too` and `long]` are in the portlist. The
 string seems to have been split on whitespace and then inserted into a
 set, resulting in the random order.

 Fortunately it doesn't seem to cause any problems beyond mpbb list-
 subports complaining that ports by those names don't exist in the index.
