Hi Gilad,

Thanks for the report. The critical error is:

CamIFaceError: /build/astraw/libcamiface-0.5.5/src/cam_iface_dc1394.c 
(1342): libdc1394 err -17: Invalid feature

This tells me something strange is going on with your camera -- it seems 
to be advertising that it has a certain feature, but then when the value 
of that feature is asked, it returns an error, saying the feature is not 
supported. (I'm not sure what the feature is -- everything such as 
shutter speed and gain are all features.)

Can you install the "camiface" package (if it's not already) and then, 
from the command line run:

/usr/lib/libcam_iface/example/simple-dc1394

Ideally, you should get an image in the directory you ran it from 
("image.ppm" or "image.pgm"). However, I suspect you'll get an error 
similar to what you just sent, but I'd like to try to narrow this down a 
bit. When you get the error can you send all the text printed to the 
console? From there, I can attempt to debug further.

As another test, can you try installing and running "coriander"?

Thanks,
Andrew
