Trying to delete backdrops leads to GUID error

[C.S. 64]

Context: For some time now, since updating to 4.8.3, I've been methodically refreshing metadata (replace all + replace images) for my TV and movie libraries in order to take advantage of the new image cache feature. I say "methodically" because I can't refresh an entire library at once, since I noticed Emby has a habit of sometimes re-identifying titles which I have previously corrected from a mis-identification. What I do is I take a screenshot of a bunch of posters, multi-select them and refresh. Then I go hunt down anything that got moved. Yes, it's a pain, but that's not the problem.

The problem, which I believe started with 4.8.5, is when I go to Edit images and add a new backdrop, I get an error when trying to delete the old one. (And I get the same error when trying to delete the new one I just selected.) I performed this operation successfully on at least 2000 movies before the error started to pop up. At first it was just once in a while, but now I can't delete any of the backdrops I've tried. (Deleting them in windows explorer still works fine.)

The error: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

This is the text generated in the log when I click Delete:

I noticed this line: at System.Guid..ctor(String g) is kind of weird. It looks like it wants to say Actor but the A has been replaced with a dot. Of course that could have nothing to do with anything, I just thought it looked wrong.

Will have to look but is this from a specific client?

Have you tried a different client?

Issue was seen in Linux ET 3.0.19 and required uninstall reinstall mentioned later in that topic.

Appears to be similar/same issue "/emby/Items/71503_ItemImage_undefined_1/Images/Backdrop/1/Delete"

Seems to work fine in Chrome. No joy in Firefox. Thanks I should have thought to check that.

Does seem odd as I would think all browsers would be using the same code/method.  But maybe @Luke has an idea unless it is a browser cache issue.

You did it again. Cleared the cache, restarted firefox and now it works. Sorry for the unnecessary post!
