Given someting like
/photo/Darkroom/DSC_1234.NEF
/photo/Darkroom/DSC_1234.NEF.xmp
/photo/Darkroom/DSC_1234.jpg
the current ingest routine fetches all files to a new dir an properly renames the NEF and jpg. Unfortunately, it misses to rename the xmp file.
With the above input the current result looks like
/photo/R/R001/R20120201_1234.NEF
/photo/R/R001/R20120201_1234.jpg
/photo/R/R001/DSC_1234.NEF.xmp
Due to this, the connection between the original RAW and it's sidecar file gets lost, which is unfortunate if one would like to later reprocess the RAW starting out with the editing done to get R20120201_1234.jpg. The funny .NEF.xmp reflects darktables default for sidecar handling. (In principle one could also have an additional .jpg.xmp if one ueses darktable for lossless jpg editing.)
