Occasional crash when selecting items from shell appmenu
Shell is occasionally crashing when I activate a Geary menu item from the shell app menu.
I only recall noticing it happening when activating Preferences or Accounts (both of these bring up dialog windows), and haven't noticed it with other menu items or other apps (although that might be because I use the app menu more in Geary when developing it). So it might be related to the dialogs, because of something stupid Geary is doing, or a bug somewhere else, but it's a bit of a pain since its takes out my complete Wayland session with it when it goes.
I finally managed to get this back trace for the crash under X11 (although it occurs under both X and Wayland).
The following was printed on the console several times by shell before the crash (with different instance addresses), but not immediately preceeding the crash that produced that back trace. I'm currently testing out changes to the Accounts dialog, so they may correspond to the Accounts menu item being successfully activated a number of times without the crash occurring.
