Builder crashes if you open 2 instances of the same project and close the second one as it is opening
- Open a project in GNOME Builder (done via the Recent Projects list in my case)
- From within the project view, press the overflow menu and subsequently Open a Project...
- From the dialogue that pops up, open the same project again (also done via the Recent Projects list in my case)
- While the project is loading, close the new instance of GNOME Builder
- Observe a crash
Note that this is very timing-dependent. Close the new instance too quickly and it'll work fine, do it too late and it'll work fine too, but I'm still consistently able to reproduce it.
