Description Tom Chiverton 2018-02-05 20:17:23 UTC

* install redshift and the plasmoid

* place the plasmoid on the task bar.

* logout and back in again

* redshift appears on task bar

* sudo dpkg -r redshift 

(removes package with no errors)

* logout and back in again

no plasma task bar appears (!)

Plasmashell should tolerate plasmoid failures without crashing.

We can't have plugins without the drawbacks of having plugins. If you have code executing in your process, there is nothing we can do to prevent freezes or blocks.

I do have some WIP on out-of-process plasmoids, but that is not within in the scope of a bug report. 

Please do file a bug with the redshift applet maintainers.

I think you misunderstand ?

Where's the bug tracking a fix ?

You are right you can fix this by out-of-process plasmoids.

But a simpler and maybe more immediate fix would be making the redshift plasmoid explicitly and safely check dependencies and do something safe if they are not met, surely ?
