Looks like this is only to call the pre hijacked one if not on os, so probably OK and similar probably should be done for all of these hijacked functions.

Fixed for me by the following package upgrades fixed the problem for me: overlay-scrollbar (0.2.16+r359+14.10.20140625-0ubuntu1 = 0.2.16+r359+14.10.20140625-0ubuntu2~utopic1) overlay-scrollbar-gtk2 (0.2.16+r359+14.10.20140625-0ubuntu1 = 0.2.16+r359+14.10.20140625-0ubuntu2~utopic1) overlay-scrollbar-gtk3 (0.2.16+r359+14.10.20140625-0ubuntu1 = 0.2.16+r359+14.10.20140625-0ubuntu2~utopic1) Before that, the problem actually went away by *enabling* rather than disabling the overlay-scrollbars (overlay-auto instead of normal) Also see https://bugzilla.gnome.org/show_bug.cgi?id=738073 ** Bug watch added: GNOME Bug Tracker #738073 https://bugzilla.gnome.org/show_bug.cgi?id=738073 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386255 Title: devhelp and many other apps crash with SIGSEGV in g_closure_invoke() due to overlay-scrollbars To manage notifications about this bug go to: https://bugs.launchpad.net/overlay-scrollbar/+bug/1386255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

For the record, I had overlay scrollbars disabled ('gsettings set
com.canonical.desktop.interface scrollbar-mode normal') when I saw these
segfaults.

[Bug 1386255] Re: devhelp and many other apps crash with SIGSEGV in g_closure_invoke() due to overlay-scrollbars
Details about my GDB session: - gdb gnome-calculator (easy to trigger the bug: click on the titlebar dropdown; bonus: doesn't hold a keyboard/mouse grab when it gets frozen by gdb) - 'run' - click on the titlebar dropdown, see the window freeze - gdb shows a segfault at 0x0 - 'bt' shows the stack trace; frame #1 is g_closure_invoke; the closure pointer is the same for every crash - higher up in the stack you see it was called by gtk_grab_notify() - set a conditional breakpoint 'b g_closure_invoke if closure == 0x' - 'run' to restart - click on the titlebar dropdown again - the breakpoint trips three times; first two are benign so hit 'cont' twice; the third one causes the crash - single-stepping with 'n' and 's' shows that you end up in g_type_class_meta_marshal() for GtkScrollbar, with a callback at some address (0x7fffeeb3abe0) - gdb was unable to resolve that address to a symbol, but /proc/$(pidof gnome-calculator)/maps shows it was in the range mapped to /usr/lib/x86_64-linux-gnu/gtk-3.0/modules/liboverlay-scrollbar.so -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386255 Title: devhelp and many other apps crash with SIGSEGV in g_closure_invoke() due to overlay-scrollbars To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-gnome/+bug/1386255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1386255] Re: devhelp and many other apps crash with SIGSEGV in g_closure_invoke() due to overlay-scrollbars
Here's what causes the crash: - overlay-scrollbar's gtk_module_init() does this: widget_class = g_type_class_ref (GTK_TYPE_SCROLLBAR) pre_hijacked_scrollbar_grab_notify = widget_class-grab_notify; In GTK+ 3.14 widget_class-grab_notify for GTK_TYPE_SCROLLBAR is NULL. - overlay-scrollbar's patch_scrollbar_class_vtable() does this: if (widget_class-grab_notify == pre_hijacked_scrollbar_grab_notify) widget_class-grab_notify = hijacked_scrollbar_grab_notify; Since widget_class-grab_notify is still NULL and it is equal to pre_hijacked_scrollbar_grab_notify, we install our own signal handler. - overlay-scrollbar's hijacked_scrollbar_grab_notify() does this: if (use_overlay_scrollbar ()) return; (* pre_hijacked_scrollbar_grab_notify) (widget, was_grabbed); Since in Ubuntu GNOME use_overlay_scrollbar() returns a false value due, this code calls a NULL pointer and segfaults. A more future-proof fix would be to check all pre_hijacked_ handlers before calling them. ** Also affects: overlay-scrollbar Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386255 Title: devhelp and many other apps crash with SIGSEGV in g_closure_invoke() due to overlay-scrollbars To manage notifications about this bug go to: https://bugs.launchpad.net/overlay-scrollbar/+bug/1386255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

GtkScrollbar stopped paying attention to grab_notify signals in upstream commit 26dff0d7830b45b61fb424e4a5c1f98c4091 somewhere in 3.13.x.
