Comment 1 Fabian Vogt 2018-10-15 14:19:21 UTC 
I can't reproduce that issue here.

Please install valgrind and upload the output of "valgrind plasma-discover".
Comment 2 Maxi Schimmel 2018-10-20 13:11:24 UTC 
Hi, thanks for your help and interest.
Today I notice that all time when I tried to start Discover had opened 'zypper sh'  on a konsole tab.
I closed it and Discover starts fine.
Can you try the same combination?
Thanks!

Still working fine here. Discover shows the "System management is locked by the application with pid 31551 (zypper)." message as expected.

Comment 6 Maxi Schimmel 2018-11-08 15:11:40 UTC 
Andrew, thanks for your comment. I sent an attachment with valgrind output.
I apologize but I don't have any knowledge about valgrind's output.
Comment 7 Christoph Feck 2018-11-08 16:38:46 UTC 
Information was provided with comment #4, changing status for inspection.
Comment 8 Aleix Pol 2018-11-08 17:26:00 UTC 
There's not much we can do with this valgrind output. Maybe passing --track-origins=yes would help?

Also there's a memory management issue fixed in KF 5.51 Kirigami, I would suggest updating to it.
