The problem comes from a corrupt ~/.local/share/mime folder. Unfortunately I have deleted the folder... I will see if I have a backup somewhere if you need to reproduce
Marking as invalid for now, reopen if you wish.

*** Bug 338653 has been marked as a duplicate of this bug. ***
Hello! We are working on a new clang-based C/C++ language plugin for KDevelop 5 which supersedes the old C++ plugin in KDevelop 4. See e.g.: https://www.kdevelop.org/news/first-beta-release-kdevelop-500-available Due to a lack of manpower, we cannot fix bugs in the old C++ plugin. We rather want to supply a good Clang based C++ experience for KDevelop 5 than wasting our time on the legacy C++ support for KDevelop 4. With the new clang-based C/C++ language plugin, the bug presented here does not occur. In my testing. For these reasons, I'll close this bug. Please stay tuned for KDevelop 5. If you think this bug is applicable to Clang/KDevelop 5, please reopen the report and add new information on how to reproduce the bug there.
