Application: kile (2.9.92)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.19.8-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
1) Create a kile project
2) Add a subdirectory to the project folder (in my case it is ./figures/)
3) Put a (La)TeX source file into the subdirectory (in my case I have each TIKZ-figure in a seperate file in ./figures/)
4) Try to add this file to the project

KILE segfaults

Please note: It does not matter how you try to add the file to the project. Menubar > Project > Add files, or open the file in editor and then right click on the tab header in the editor and then select "Add to project" from the context menu, or right click on the file in the directory view at the right and select "Add to project" from the context menu. It always segfaults.

The crash can be reproduced every time.

-- Backtrace:
