Wasn't that clear? I'm still running 5.8 *with* the fixes.

This does look like a related-but-different issue though, trying to disconnect a 
valid receiver from a sender instance which has apparently already been deleted.

It appears to be an issue caused by (with?) the QtCurve widget style, though.

FWIW, this is what I get for the receiver object:
