Comment 1 for bug 1838593

Hello,

I can't replicate the error on Ubuntu. Any way, is not a QtQR bug/problem,
there's something that zbar (the library we use to decode using the webcam)
that doesn't like about your webcam or the driver you are using. Please try
using zbar directly and let me know if you have the same error, if you do
please report the bug to them. If you don't, we can see if there's
something we can do from the QtQR side.

Thanks.

Regards,
