I clicked it to launch Discover so that I could apply the updates. The Discover window displayed briefly (about 2 seconds) in an incomplete state, and then went away. A crash handler popped up just before the Discover window disappeared. The crash can be reproduced every time. -- Backtrace: Application: Discover (plasma-discover), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
