Comment 1 Nate Graham 2020-10-12 20:49:15 UTC 
Is this still happening with Frameworks 5.75 if you try again? The dialog got a lot of fixes recently for updating items.
Comment 2 Patrick Silva 2020-10-16 13:04:37 UTC 
it's no longer happening, despite update of addons is failing (they reappear when I reopen GHNS windows).

Comment 3 Nate Graham 2020-10-16 14:04:32 UTC 
Oh good. Let's use a different bug to track that issue. :)

Discover saying "file not found"

This crash occurs when the color scheme that I'm trying to update is not found.
At least Discover shows an error message, as we can see in the attached screenshot.

Comment 5 Alexander Lohnau 2020-11-26 19:10:05 UTC 
Is this still reproducible?
Comment 6 Nate Graham 2020-12-01 18:04:46 UTC 
Crash log looks to be entirely in non-KDE code. If it's still happening, I would recommend filing a Qt bug report.
