Comment 1 Kevin Funk 2017-07-24 07:27:36 UTC 
I can't reproduce this in KDevelop 5.1 branch.

Could you install debug symbols for kdevplatform/kdevelop so we can see line numbers in the backtrace? 

See:

Comment 2 Scott Sloan 2017-07-24 23:55:38 UTC 
I was unable reproduce it myself. Feel free to close and I'll create a new issue if it happens again
