patched python-rawkit-0.6.0-5 in community-testing, how does that one behave?

Yes, I now can instantiate the class and run some operations, thanks.
There appears to be some bug with raw.save() as a TIFF file, but raw.save() as PPM file is fine. Probably an upstream bug and nothing further to do here, but let me report the Traceback in case Jaroslav/other experts know better:

In [35]: from rawkit.raw import Raw

In [36]: r = Raw(filename='7223.nef')

In [37]: r.save(filename='7223.tiff')

Ok, thanks for the quick reply!
Also, unfortunately not much expertise on the next issue, I'd say reporting it upstream will be the best way to go, if not done yet.
Cheers!
