Python Exception <class 'gdb.error'>: value has been optimized outSeems to be crashing with an excess of file handles, and seems to only happen if the battery widget is in the panel somewhere.

The first place this is noted is in window-list widget, here is the bt with asan:
To repro:
run wayland nested backend with
WLR_WL_OUTPUTS=2 wayfire -d -c /tmp/wayfire.iniwhere wayfire.ini hasipcandstipcplugins enabled. Then clone https://github.com/ammen99/wayfire-tests and cd into wayfire-tests/wfpytest/ and run this script with python3:Expected: wf-panel does not crash
Actual: wf-panel crashes with above backtrace
