Judging from the commit message, it looks like some uninitialized 
variables related to UVW coordinates.

The fix is in CVS.  It has been applied to the 2.1 branch, the 2.2 
branch, and the latest development version.  (This bug has been around 
but hiding for a LONG time - at least since EMC 2.1.0, in January of 
2007.)  When the next binary packages (version 2.2.8) are released, they 
will contain the fix.

No date has been set for the 2.2.8 release.

Two reasons the bug wasn't fixed before:

1) It is extremely rare - just the right (wrong?) conditions are needed 
to trigger it.

2) We never got good detailed information about the bug before, and were 
never able to reproduce it.  Kudos to Stuart for the detailed reporting!

Regards,

John Kasunich
