Twice this morning, my web process crashed due to bug #235224. Each time this happened, the UI process also crashed: (gdb) bt #0 0x00007f888d10108a in webkitWebViewBaseSnapshot (snapshot=0x55d8daf41800 [GtkSnapshot], widget=0x55d8da5b8f30 [EphyWebView]) at /usr/lib/debug/source/sdk/webkit2gtk-5.0.bst/Source/WebKit/UIProcess/API/gtk/WebKitWebViewBase.cpp:732 #1 webkitWebViewBaseSnapshot(GtkWidget*, GtkSnapshot*) (widget=0x55d8da5b8f30 [EphyWebView], snapshot=0x55d8daf41800 [GtkSnapshot]) at /usr/lib/debug/source/sdk/webkit2gtk-5.0.bst/Source/WebKit/UIProcess/API/gtk/WebKitWebViewBase.cpp:716 #2 0x00007f8890c7acc1 in gtk_widget_create_render_node (widget=widget@entry=0x55d8da5b8f30 [EphyWebView], snapshot=snapshot@entry=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:11582 #3 0x00007f8890c7da0c in gtk_widget_do_snapshot (widget=widget@entry=0x55d8da5b8f30 [EphyWebView], snapshot=snapshot@entry=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:11622 #4 0x00007f8890c8b2c3 in gtk_widget_snapshot_child (widget=<optimized out>, child=0x55d8da5b8f30 [EphyWebView], snapshot=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:12043 #5 0x00007f8890b6f3bd in gtk_overlay_snapshot_child (snapshot=0x55d8daf41800 [GtkSnapshot], child=0x55d8da5b8f30 [EphyWebView], overlay=0x55d8da10b370 [GtkOverlay]) at ../gtk/gtkoverlay.c:202 #6 gtk_overlay_snapshot (widget=0x55d8da10b370 [GtkOverlay], snapshot=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkoverlay.c:225 #7 0x00007f8890c7a8c0 in gtk_widget_create_render_node (widget=widget@entry=0x55d8da10b370 [GtkOverlay], snapshot=snapshot@entry=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:11587 #8 0x00007f8890c7da0c in gtk_widget_do_snapshot (widget=widget@entry=0x55d8da10b370 [GtkOverlay], snapshot=snapshot@entry=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:11622 #9 0x00007f8890c8b2c3 in gtk_widget_snapshot_child (widget=<optimized out>, child=0x55d8da10b370 [GtkOverlay], snapshot=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:12043 #10 0x00007f8890c8b36e in gtk_widget_real_snapshot (widget=0x55d8d96aabd0 [EphyEmbed], snapshot=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:734 #11 0x00007f8890c7a8c0 in gtk_widget_create_render_node (widget=widget@entry=0x55d8d96aabd0 [EphyEmbed], snapshot=snapshot@entry=0x55d8daf41800 [GtkSnapshot]) at ../gtk/gtkwidget.c:11587 ...
