Do you always get this crash?
If so which are the steps?

Would it be possible to get a backtrace with symbols?

Comment 6 Christoph Feck 2018-07-18 16:29:36 UTC
If you can provide the information requested in comment #5, please add it.
Comment 7 Lewkow Brigitte 2018-07-19 00:49:47 UTC
Adding infos:
Usually i uses synaptic. Then to answer, i've just used plasma-discover again and it seemed working well, navigating on the proposed items ! All icons had responding as expected except when some screenshots were not available while it was previously (before surfing on links) available ! Not so important but when i wanted to close plasma-discover by clicking on the the close-cross it hanged and the window began to be transparent (print the firefox window) with Firefox ! And in the following seconds, the bug-crash-report appeared two times, first with plasma-discover and then with korgac ! I took two screenshots (because it was automatic, can't select text as you know, just collapse). In the plasma-bug-report, the last line refer to Firefox (dconf warning) and snapd (unable to open..., permissions denied...).
Comment 8 Lewkow Brigitte 2018-07-19 01:09:05 UTC
I've just retry: opened and closed (without installing anything) twice plasma-discover and it worked normally . 
I don't know if it can help but concerning my previous message, i installed two packages and even could installed some in synaptic while discover was open ! It seemed that discover didn't lock the install process ! Surprising, no ? Yes ? Muon blocks the install process usually, but sometimes it could be possible to install some packets with synaptic while muon-update is on. I don't if this kind of use is reasonable.
Comment 9 Christoph Feck 2018-08-02 17:26:27 UTC
Thanks for the updates; changing status.
Comment 10 Aleix Pol 2018-08-03 14:32:37 UTC
The original issue is solved, closing.

Lewkow, would it be possible for you to report your issue and get a backtrace for the frozen discover?
