"g_strstr_len: assertion 'haystack != NULL' failed" criticals when changing VM resolution
Description
I run a VM with QEMU/KVM. When I change the VM's resolution, I get criticals like this:
(thunar-volman:1775): GLib-CRITICAL **: 21:44:46.014: g_strstr_len: assertion 'haystack != NULL' failedDebugging
Here's an example invocation that causes criticals: thunar-volman --device-added /sys/devices/virtual/input/input12/mouse2
It looks like the VM returns NULL for the mouse-model:

(gdb) p id_model
