That's the behaviour I'd expect if the raw format is not recognised (dt can do previews because those are initially based on the JPG preview that's embedded in the raw files). Indeed, I don't see any references in the source code (even of the development version) so I'd say it has simply not been added yet. If you can provide samples, I'm sure that situation could be fixed, though.
For a list of the samples required, see here: http://www.darktable.org/2012/10/whats-involved-with-adding-support-for-new-cameras/ This normally boils down to one sample raw for basic support, plus a raw/jpg pair for each white balance preset, but can involve more files to support other more interesting hardware features if they're present.
