Could you try to modify the file in /lib/udev/usb_modeswitch, and change the third line from the end to:
exec ltrace /usr/sbin/usb_modeswitch_dispatcher "$@" >/tmp/ltrace.txt 2>&1 & (take a backup of the file first). Then try to connect the dongle again (without the Mobile Partner of course); and attach /tmp/ltrace.txt to this bug report when it crashes. This should tell us more about where things break.
