compare, deleting doesn't work

[svennbg]

I have two photos, one of which has the extension jpg and the other bak.
I call up the Compare function.
I then click on the delete icon to delete the photo with the bak extension. See red marking.
A prompt appears, which I confirm.
But the photo is not deleted afterwards.

you are able to reproduce each time?

[svennbg]

yes,
I have just copied another jpg file into a new folder.
Then I made a copy of the jpg file and renamed it to .bak.
The problem has reappeared.

By the way:
My version is 1.6.2 64-bit (Windows)
