4. Replicate a environment and run the test inside gdb. What you need here depends on the test that needs investigation. In the simplest case, the following is enough:
4. Run the test case
```sh
meson test -C build failing-test-case
```
5. Run the test case in gdb
```sh
export XDG_RUNTIME_DIR=$PWD/runtime-dir
mkdir -p $XDG_RUNTIME_DIR
./src/tests/meta-dbus-runner.py meson test -C build --setup plain --gdb failing-test-case
```

```sh
export XDG_RUNTIME_DIR=$PWD/runtime-dir
mkdir -p $XDG_RUNTIME_DIR
./src/tests/meta-dbus-runner.py bash -l
