I have probably similar problem, after updating spice-server (from git
for test lz4 support), spice-gtk, virt-viewer and usbredir (all to
latest stable version) I also have always qemu crash with a deadlock on
latest log line when I remove an usb device on both remote-viewer and spicy.
I use ubuntu 14.04 as client with updated packages from this ppa:

Here the backtrace of qemu crash:

Another strange thing is spicy-stats segfault refering to usbredir also
without any usb devices redirected, here a backtrace:

Can you take a look to this problem please?

If you need more informations/tests tell me and I'll post them.

Thanks for any reply and sorry for my bad english.
