Updates:

I've tried to reproduce the issue with Chameleon build in between 
stated last known working version (r1242) and the version that 
causes the issue (r1518)

Test results:
Highest version that works before the issue occurs is r1516

Only the most recent build (r1518) have this issue. I'm not sure of 
the changes committed to this build but I hope this helps.

Cheers.
