Valgrind trace

SUMMARY
When starting spectacle (no matter how, using the CLI, the app launcher or the impr screen shortcut), it immediately crashes.

Attached are another Valgrind trace
Here is a link to a coredump (~750MB) : https://gitlab.gottagofast.fr/LouisDupraz/storage/-/blob/5cee5e00627396ba525fbf06f342c787c0d2fe6d/trace.txt.core.706428

STEPS TO REPRODUCE
1. Launch Spectacle

OBSERVED RESULT
Spectacle does not start (GUI does not appear) and a crash message appears

EXPECTED RESULT
Spectacle starts
