Talking in discord causes "JS ERROR"

[John Ingve Olsen]

Whenever I talk in discord, the system log is spammed with the following message and error:

discord1, Impossible to lookup icon for 'discord1_38-panel'

The error message that is logged:

JS ERROR: Exception in callback for signal: icon: Error: Argument 'filename' (type filename) may not be null
_createIconByName@/<email address hidden>/appIndicator.js:406:26
_cacheOrCreateIconByName@/<email address hidden>/appIndicator.js:368:14
