The printer has always been working before, Canon IR2520. After upgrade to 27 the job is hanging in "Processing" state, and the printers application crashes. I see some errors in the logs like:

Nov 24 13:08:14 ksy kernel: cnpkmoduleufr2[3582]: segfault at 0 ip 00000000f7d73d33 sp 00000000ff962d80 error 4 in[f7ce5000+1ba000]

and then stack trace:

I tried to look for a bug but haven't found any. Does anybody have the same?
