We have noticed an issue which occurs rarely. Unfortunately I am not able to reproduce it and do not know how I could debug this further.
Sometimes when the greeter starts the global variables lightdm, greeter_config, theme_utils, etc. are not defined. This results in an exception in the theme and shows the "Detected a Theme Error" modal dialog on screen. Reloading the theme or loading the fallback theme does not help in this case. To resolve the error, the greeter process has to be killed:
killall lightdm-webkit2-greeter
Manual examination using the debug console shows that the variables are undefined.
Greeter Version: 2.2.5 OS: Ubuntu 18.04
