I cannot reproduce your backtrace. Are you still able to see your backtrace?

Hi, fujiwara, backtrace now is not reproducible because it seems that after an upgrade abrt not recognize the error. "Oops, ......" disappeared. Going from cinnamon-session to gnome-session with the same user there are no more errors. Just as well. I do not know why, but now everything seems to work regularly. Thank you. Ciao :) Sergio
