Collect Images module tags list out of sync
The list of "darktable|..." tags available in the Collect Images module can become out of sync. For example, I start with an empty library. I import some raw files and some JPEGs. Two available tags are "darktable|format|cr2" and "darktable|format|jpg". I remove the JPEG files from the DT library. The "darktable|format|jpg" tag remains in the list. Collecting images with it leads to the message "there are no images in this collection." I would have expected that "darktable|format|jpg" would no longer be in the list of tags.
