Hello! Recently I’ve upgraded to nixos 24.05 and got telegram-desktop segfault on strtup. I run it under valgrind:
nix run nixpkgs#valgrind -- /nix/store/3ssgh296jf5nahmdzsmdb1irg02qwaxz-telegram-desktop-5.1.7/bin/.telegram-desktop-wrapped
And got stack leading to adwaita. I disabled adwaita-dark theme, unsetting QT_STYLE_OVERRIDE. Then I got segfault leading to xkb. Having no idea what to do next yet.
Stack fragment from first run (with adwaita problem):

Does anyone have an idea where to dig next? Thank you!
P.S. Version from nixos 23.11 (telegram 5.0.1) works well: nix run github:NixOS/nixpkgs/nixos-23.11#tdesktop
