Hello,

thanks reporting and for laborious troubleshooting.

I just did a commit for it, seems nobody was using profiles with no value for long time. Can you try the patch from commit 028e3cc1a34f1e682d604a7c0e3fb1a7da03a211 done on GIT master?

If all ok, I will backport.

Cheers, Daniel

looks like 3.1.0 + 028e3cc1a34f1e682d604a7c0e3fb1a7da03a211 resolved the problem.

thanks,
