Created attachment 608582 [details] backtrace I am getting crashes every time that I try to show the print dialog with applications that use GTK (tried Firefox and Evince). The attached backtrace looks very similar to that described in https://gitlab.gnome.org/GNOME/gtk/merge_requests/1346, and indeed applying the patch from https://gitlab.gnome.org/GNOME/gtk/commit/3d5f083b75a0c2b50fb5528a19e0e095e85a438e solves the issue for me. I can reproduce this problem with gtk+-3.24.13, but I do not recall having any trouble with earlier versions.
