Description Mayeul C. 2018-10-02 09:13:45 UTC 
Application: plasma-discover (5.13.5)

Qt Version: 5.11.2
Frameworks Version: 5.50.0
Operating System: Linux 4.18.10-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

Writing a comment on bug 385754, I clicked the "Update" button mutiple times (opening Discover, then closing it, reopening it...), and Discover crashed at some point after clicking it.

I might have clicked on "check updates" in the client before closing it.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
