dom0 widget-wrapper error/traceback during dispvm cleanup

[rocodes]

How to file a helpful issue

Qubes OS release

4.2.2

Brief summary

In the dom0 journal I notice a Python traceback pointing here when dispvms are cleaned up. I initially noticed this when the VM shuts down prematurely (eg, trying to open a file in a dispvm that doesn't have an appropriate mime handler), but this also occurs in normal shutdown of dispvm and I observe it every time.

Steps to reproduce

Start then shut down a disposable vm while watching dom0 journal

Expected behavior

Clean shutdown

Actual behavior
