Extension Causes Intermittent Live Locks #115

Please provide the shell and extension information. It will be easier for me to understand the issue without too many unnecessary questions

Describe the bug (See below.)

Extension Information

Error / Journal messages

Some code accessed the property 'SoundDeviceChooserBase' on the module 'base'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.

Suspecting that one of my Gnome shell extensions was causing the live lock of my Ubuntu 18.04 workstation, I disabled each of the four extensions I was using:

  1. Cast to tv
  2. Gsconnect
  3. Sound input & output device chooser
  4. Workspace grid

By "live lock," I am referring to a non-responsive system whose front panel disk access light is solid on. Sometimes the mouse cursor will respond to a mouse movement, but nothing else. Eventually, perhaps 5-10 minutes later, the workstation returns to its normal responsiveness.

After disabling the four extensions, I used the system for a week and observed no live locks.

Then, I re-enabled Gsconnect, used the system for a week, and observed no live locks.

Then, I re-enabled Workspace grid, used the system for a week, and observed no live locks.

Then, I re-enabled Sound input & output device chooser. Within a minute of re-enabling the extension, the workstation live locked.

Hence, we see strong evidence that the Sound input & output device chooser Gnome shell extension on my Ubuntu 18.04 workstation leads to a live lock, leaving the machine unusable.

This error was fixed in later extension version, but 3.28 had other compatibility issues, so I removed it from the list. I will see if I can fix it.
