Is this crash reproducible for you? How, with what files? It does not cras here.
Comment 2 Sandeep 2018-08-16 17:57:38 UTC 
I haven't been able to reproduce the crash so far. It was just a random crash that happened one time.
Comment 3 Sven Brauch 2018-08-16 18:55:31 UTC 
Pretty sure this is a duplicate of what Dominik fixed yesterday in KTextEditor.
