YES! You are right!

The problem lies in a higher up directory. There is a permission 
problem. Just make a full functional root session and checked the 
/var/run/schroot/mount dir and found this:

drwx------ 22 root root 4096 sep 22 14:09 
stretch-amd64-sbuild-23013978-edff-4e90-a6d9-984da3bd4dd6

The normal users can't access that dir (the root dir).

Should this be fixed in /etc/schroot/setup.d/10mount?
