SIGSEGV on exit in libgtk-4.so.1

[toiletbril]

Hello! Thanks for the awesome terminal. I use it a lot.

Lately, I noticed that all ghostty windows close when trying to close just one window. Upon some investigation it appears due to a segfault.

This bug was not present on 1.0.1, and appeared in 1.1.1, persited to 1.1.1_1 from xbps (package manager). Below are the details.

OS:

Void Linux 6.12.13_1

Packages:

glibc 2.39_4
zig-0.13.0_1
libadwaita-devel-1.6.4_1
gtk4-devel-4.16.12_1

Reproduction steps:

1. Install from the package manager or build from source (HEAD is initially 315df0a, bug is still present on 6d8db4b).
2. Run ghostty, then exit any of the windows (click X on the window decoration or run exit):

Does this happen when you dont disable adwaita, if not then It wont be much of an issue since ghostty will adwaita only going forward into 1.2

[toiletbril]

What is the name of the setting in question? gtk-adwaita is long gone in 6d8db4b.

[rhodes-b]

Yet your log does not show printing the adwaita version like it should be which meants you had it disabled

[toiletbril]

Seems like this issue is to be fixed in #5781. Let's wait.

[pluiedev]

Does it still occur after the linked PR had been merged?
