Description Antonio Rojas 2018-09-17 06:46:36 UTC
When clicking "Magage application" from kicker context menu, discover takes a really long time (1 minute here) to display the application. It seems that it doesn't do it until it's done checking for updates, which can take a long time.

Cannot reproduce with git master on Neon or 5.12.6 on Kubuntu 18.04. It's near-instant for me on these systems.

It depends on which backends and providers you have installed (in my case, the offending one is the knsrc from kalzium). The issue is not how long it takes, but the fact that nothing is displayed until the check for updates is finished for all backends (which may potentially take a long time).
