Description of problem:
Nautilus will segfault during startup if I load either the usb modules
or the sound modules. Runs normally (except for the fact that I have
no mouse) otherwise.

This wasn't an issue until I got kudzu working.. I'm currently running
kernel 2.6.4-1.305 prior to that I could load the usb module to get
the mouse working.  This might be related to a usb webcam I have
connect to the computer (it has a builtin mic and is detected as a usb
soundcard).  I've tried disconnecting the cam, but still get the
segfault during startup if the usb module is loaded.

my /etc/modprobe.conf currently looks like this:

alias eth0 tg3
alias scsi_hostadapter aic7xxx
alias scsi_hostadapter1 sata_via
alias If you're having problems with gated making 127.0.0.0/8 a
martian, tg3
#alias sound-slot-0 snd-emu10k1
#install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
#remove snd-emu10k1 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ;
}; /sbin/modprobe -r --ignore-remove snd-emu10k1
#alias usb-controller ehci-hcd
#alias usb-controller1 uhci-hcd

all that is output in /var/log/messages for the segfault is:

kernel: nautilus[2526]: segfault at 00000004fffffff8 rip
000000312d46a105 rsp 0000007fbfffed70 error 4


I tried strace to figure out what it's doing, but I'm not that
familiar with the tool, and didn't see anything obvious in the
output...  Let me know what I need to do to provide you with better
information.

nautilus-2.6.0-1

How reproducible:

Steps to Reproduce:
1. modprobe uhci or ehci or snd-emu10k1
