Rick has stated he is looking into this but has not re-stated he found or did not find a issue.
But in any case Rick also stated that v7.5.3 would be stalled a little bit to try to address as many discovered bugs on v 7.5.2 as possible.
I assume so he can devote more time with version 8 instead of flipping back and forth to v7 for bug fixes.
