Description Jaime Torres 2018-09-14 10:37:06 UTC

Application: kdevelop (5.3.40)
 (Compiled from sources)
Qt Version: 5.11.1
Frameworks Version: 5.51.0
Operating System: Linux 4.18.5-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

Editing kfileitemmodel.cpp or placespanel.cpp. Double clicking over a word and pasting a replacement.

In the stdout:
libclang: crash detected in code completion
kdevelop.languages.clang: Something went wrong during 'clang_codeCompleteAt' for file "/home/jtorres/kdesrc/kde/applications/dolphin/src/kitemviews/kfileitemmodel.cpp"
