As you know, I've been shoe-horning my photos into MC. It's a project I've started numerous times, with plenty other software trials inbetween. Anyhow, things with v11.1 are gathering momentum thanks to some creative expression writing :)
I was just beginning to think about ditching the copies I've been messing with, when I came across this.
Many of the photos dates are wrong in MC, despite the exif info being present. I discovered that, if there's an <MJMD> tag present in the file, the "Update library from tags" tool won't re-read the EXIF info.
So, as I couldn't see a way to filter only files that have an <MJMD> tag, and after testing on a single file first, I selected the whole lot and removed their tags, then re-ran the update library from tags tool to get the right dates. Worked a treat, and got rid of a load of testing tags debris in the process. Except...
I've found quite a few corrupt files. For some reason, when removing the tags from these files, MC is damaging them, or perhaps they are already damaged, so MC can't handle them correctly? All I can say is that after removing the tags, the image can no longer be viewed.
Both v11.1 and v12 behave in the same way.

click the image to d'load a .zip containing the original, with tags, and and a corrupted version after tag removal. (0.9 mb)
If possible, I would like to know what's wrong.
Is it all MC's fault, or only partly?
if only partly, what else, and how to fix and prevent?

EDIT:
"quite a few" is actually 135 files from a total of 1360 (Kodak photos) I chose to work with last night.
I have backups, but whatever it is that's wrong, is present in the backup files too. My image work is now on hold pending some feedback on this little hurdle.

Nice find Marko. It took a series of somewhat uncommon events to cause the issue, but it was certainly there.
Next build:
Fixed: Removing an MJMD tag from an image that had other unknown appid blocks after the tag could cause an issue.

Yeah, that sounds like me!!
Thanks Matt.
