What is the actual problem you are reporting?
A lot has happened upstream since the bug that you've cloned - in particular using add_copy_spec_limit() with directories, or globs that expand to include directory paths, is now forbidden and no current plugins do this.
If you are seeing specific problems with any plugin shipped in the sos package please detail them - otherwise this is NOTABUG.
In that case the bz you are looking for is bug 1002619 - "Add syslogsize option and an appropriate default value to the sosreport gluster plugin".
This bugzilla is about the size limiting APIs themselves and affected a half dozen other plugins in addition to gluster.
I'll close this NOTABUG and clone bug 1002619 for RHEL7.
