I recommend stabilizing 4.8.7 instead.

Are you sure 4.8.7 is affected? commit 9c575cb9e3ed2cefc2ec0c2324f60bcd03af2d35 should've taken care of that.

I must admit that I did not build 4.8.7. I drew conclusions only on the basis of the Qt source, so I can well be wrong on that score. However, I did ask to patch 4.8.6, if you are not going to be removed from the tree.

Thanks.
