Conflict with Search Light: GNOME Shell crashes on first Search Light use after boot

[DumbledoreCalrissian]

Describe the bug
When both Tiling Shell and Search Light are enabled, GNOME Shell crashes consistently. The crash occurs right after boot when using Search Light to launch an application. Disabling Tiling Shell prevents the crash entirely.

To Reproduce
Steps to reproduce the behavior:

1. Boot into GNOME 48
2. Have both extension enabled: Tiling Shell and Search Light
3. Immediately after login, trigger Search Light (e.g. open it and search for an app)
4. GNOME Shell crashes --> session ends, forced logout.

Expected behaviour
Search Light should work normally, even with Tiling Shell enabled.

Actual behaviour
Shell aborts (SIGABRT) and logs out.
