Lysathor, do you recall if you perhaps had closed a view shortly before this error occurred?

Comment 2 Lysathor

Sorry, I do not know what caused the errors. I think I've not closed a view, but I am not sure. 
In general, it seems to me that Juno is very slow/sluggish compared to Indigo. E.g. often Drag&Drop seems not to work but it does (but is very slow). Perhaps it is related to this?
I'm going back to Indigo for now.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
