Howto debug crashes in usb_modeswitch?

[Clemens Eisserer]

Hi,

I am running F17+updates-testing, and for some time now I experience
frequent segfault crashes of usb_modeswitch when plugging in my UMTS
usb modem (ZTE MF652).
As ABRT doesn't detect the crash and manually triggering the
modeswitch usually doesn't crash I am a bit helpless.

Is there any way to debug the modeswitch triggered by systemd?

I've filed reports about both, usb_modewitch crashing as well as ABRT
not detecting the issue, however that didn't generate a lot of
interest:
https://bugzilla.redhat.com/show_bug.cgi?id=875511
https://bugzilla.redhat.com/show_bug.cgi?id=872304

My experience with running fedora-beta or updates-testing is not the best.
I am prepared to file bugs when something goes wrong, however usually
nobody cares :/:

Thank you in advance, Clemens
