Possible bug in recent ImageJ1.x update - losing scale information

I think I found a bug in the most recent ImageJ1.x update. I noticed that in my workflow - I was losing my scaling information at a certain stage. Comparing two different versions of ImageJ1.x: 1.51t versus 1.52m. If you use this little macro - you can see the difference between versions:

run("Blobs (25K)");
run("Set Scale...", "distance=5 known=3 unit=mm");
setAutoThreshold("Default");
//run("Threshold...");
run("Create Mask");

Also took snapshots to show issue:
29%20PM 00%20PM

I’ve got a workaround for the moment… but this needs to be addressed obviously.

Can someone else confirm this? Particularly @Wayne?

Image 1.52n fixes a regression in 1.52m that caused the Edit>Selection>Create Mask command to not preserve spatial calibration. Use the Help>Update ImageJ command to upgrade.
