Created attachment 110516 [details] unknown API error sometimes installation from kde store (icon theme, for example) fails and discover shows an error about API (see screenshot). So "task" shows progress 0% in sidebar and I can't cancel failed installation because nothing happens when I click button to do it. I need to kill discover using ksysguard. This problem occurs on Arch Linux and neon dev unstable.

Comment on attachment 110546 [details] bug recreation I can confirm this behavior on Neon Git Stable 20180210 (Plasma 5.12.0, KF 5.43.0, Qt 5.9.3). Discover window cannot be closed normally as it states "there are tasks that need to be done". Easily reproducible on mentioned example (AwOken icon pack) and I think this addon causes the problem. Currently, there is nothing to download there - https://store.kde.org/p/1012537 0 active download, 2 archived, that's why probably discover fails to download addon, as it's not accessible.
