Thank you, sound good. I will give the patch a go.

Hello guys,

We are trying to delete some docker images from our docker feed in ProGet using the web interface.
However the SQL query seems to fail, and the site throws an application error. This only affects deletion of certain image tags, not sure what makes them special.

ProGet Version 5.2.14 (Build 17)

Full error/Stack trace

Any idea how to fix this or what could be happening?
I tried deleting the image tags using the API, but this fails the same way.
