Nice catch. Might be helpful to post this as a bug report to the glib project. So they can make their software more resilient.

I managed to find the problem: ``` .@.:~/.config/glib-2.0/settings/ > diff keyfile ~/tmp/.config/glib-2.0/settings/keyfile 2,3c2,3 < window-position=(20, 20) < window-size=(679, 687) --- > window-position=(26, 23) > window-size=(4092044, 2046032) 9c9 < sidebar-width=157 --- > sidebar-width=224 .@.:~/ > cat ~/.config/glib-2.0/settings/keyfile [org/gtk/settings/file-chooser] window-position=(20, 20) window-size=(679, 687) date-format='regular' location-mode='path-bar' show-hidden=false show-size-column=true show-type-column=true sidebar-width=157 sort-column='name' sort-directories-first=false sort-order='ascending' type-format='category' ``` The file chooser tried to use an impossibly large window size, which subsequently caused it to try to allocate an extremely large shared memory blob (roughly on the order of terabytes, afaik) for the window buffer.
