Description Joshua Taylor 2017-07-02 01:03:59 UTC 
Application: plasma-discover (5.9.4)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-26-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
I was in the Developer Tools/IDEs category and searched for "kdevelop" and Discover crashed. I wasn't running anything else other than Firefox, so I don't think there was some other program conflicting with Discover.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Thank you for the report :) By the backtrace it would seem the crash is the same as in this other report, and as your version is older than the version in which the fix was released, i think it's safe to assume this is not a new thing.
