Hi Max,

Two things come to mind. Sorry if they seem odd but I suspect you are 
probably open to dumb suggestions.

First, try removing th "-" and replacing with "_" instead. Sometimes I 
find some characters are just not processed correctly (see story below).

Second, I vaguely remember similar issues being discussed on the forum. 
 From memory it related to metadata. Look at the type of metadata in the 
originals and the symbols used. Try making a copy with another package, 
say GIMP, stripping the existing metadata and try again.

If you have access to a Windows or Mac, which I presume you do as I am 
pretty sure CR2 does not run on Ubuntu, try using ExifTools 
(http://www.sno.phy.queensu.ca/~phil/exiftool/) to see if something 
different is in the metadata for the images that are being problematic.

*True Story* - I had some data I imported from Windows to Ubuntu. The 
data was raw text. I imported into LibreOffice Calc. Calc then displayed 
very peculiar behaviour with sheets being parsed mid-sheet and visually 
offset by a number of pixels. Visually it appeared the data was walking 
of the page. In the end I tracked it down to use of the degrees symbol 
(as in degrees Celsius) in the windows dataset -- once I removed this 
everything worked. Apparently this symbol differs between code pages. 
The lesson I learned from this is, where possible always use UTF-8 or 
UTF-16 code pages in text being moved around platforms otherwise stick 
to the absolute basics -- azAZ09; no symbols.
