Thanks To help you out we need see logs, on Ubuntu I think that /var/log/syslog is the best log , but you may have other on /var/log. We need to see if pppd die , and try find out if it is a ppp problem, or if it is usb problem , see dmesg , type dmesg > dmesg.txt after crash and see you you have anything new on end of dmesg.txt. USB modem k-2565-Z was worked before ? and send lsusb -v after plug your modem , to know what device we are talking about. you may should open a bug on https://bugzilla.gnome.org/browse.cgi?product=NetworkManager with all details ask before to tack down the problem.
