workaround that I have: I created an udev rule

ATTRS{idProduct}==0017, RUN+=/sbin/modprobe usbserial vendor=0x1bbb
product=0x0017

I'm also affected by this bug. I replaced the line with exec ltrace /usr/sbin/usb_modeswitch_dispatcher $@ /tmp/ltrace-$(date).txt 21 to avoid name clashes, and, as Mathieu observed, the process exited normally (meaning that the usb modem got switched, modemmanager recognized it, and network-manager was able to use it).

Well, I won't be able to get anything fixed unless we catch one such occurrence (with the ltrace log) when the modeswitch application is crashing (therefore writing its message segfault in syslog). Again, this one appears to be ending succesfully, so not much to do with it... Unless I'm missing a part here?

Hasn't this run not crashed? Please make sure you don't re-run usb- modeswitch before attaching the ltrace log; since it will get overwritten every time the binary runs.

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 21 (take a backup of the file first).

I can confirm. Same segfault happens also with Nokia CS-15 modem and Mobile Partner doesn't solve that.
