Before I answer about the xmp's: I am worried about the lack of exif info in
the original file (as well as the _v1). I'm 100% certain that darktable exports
them correctly (have never seen it fail on that). So somehow, digikam managed
to kill them. (cannot proof that, but I don't have any other explanation)

About xmp files: yes, I have enabled xmp support in digikam and darktable uses
them heavily. 
Thers are: 
DSC_7440.jpg.xmp
DSC_7440_v1.jpg.xmp
