Application: qtcreator (4.8.2)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-12-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to open a ui file in the form editor. I had also opened a second project that is in a subdirectory of the main project and has a ui file with the same name like the one I was trying to open.

The crash can be reproduced every time.

-- Backtrace:
Application: QtCreator (qtcreator), signal: Segmentation fault
