This is an error/warning from the client.
Could you try to provide with a backtrace of the client if it crashes, or of qemu if it's really the guest that crahses. thanks?
Pavel, I found the bug 1338752 to be very similar. The USB device does not have to be detached rudely,but even when detaching with remote-viewer redirection the guest crashes.
To server log right after USB detachment are added these lines:
qemu-kvm: spice-qemu-char.c:188: spice_chr_write: Assertion `s->datalen == 0' failed.

the crash is in qemu-kvm. The backtrace is attached.
The reproducer, result and the backtrace are similar as in the bug 1338752, closing as duplicate
