Cannot reproduce...
Please, follow the
rules to the letter and provide the logs !!!
Also provide a step by step recipe to reproduce the bug.
As far as I can see, there is no such bug (I cannot reproduce anything similar to what you describe), and there's no code change since v1.26.14.7 that could be related, even remotely, to what you describe (no change to object editing, in particular); if you only tested the latest release "a few minutes", I suggest you try it again and check that you are not trying to put the texture inside the prim (did you hold CTRL down while dragging and dropping the texture on the prim ?) instead of onto one of its face...
