but it is merely a if test. I don't see how that can crash at all.

Re: [Bug 2136313] Re: Pidgin crashed with SIGSEGV in g_type_check_instance_is_a()
Well, that's an useless backtrace, but it's my fault, for I hadn't selected to build and publish the debug packages in the PPA. Done that and published z4, identical to z3, but now also with the required ddebs. Please update to z4 and try again. It is possible that Debuginfod won't work for PPAs. So if the backtrace is as empty as before, the easiest way would probably be to download the ddebs manually from the build page[1] (here are the direct links: [2][3]) and then to install them with sudo apt install ./libpurple0t64-dbgsym_2.14.14-1z4_amd64.ddeb ./pidgin-dbgsym_2.14.14-1z4_amd64.ddeb Then repeat the commands.

[Bug 2136313] Re: Pidgin crashed with SIGSEGV in g_type_check_instance_is_a()
Thanks Charlie for having a look, I thought — the documentation is missing[1] — the guard g_return_val_if_fail (GST_IS_DEVICE (device), NULL); was supposed to prevent a crash instead of triggering one, but indeed I found elsewhere that 'the program is considered to be in an undefined state afterwards'[2]. As such just checking ourselves if that is actually a valid device should suffice.

[Bug 2136313] Re: Pidgin crashed with SIGSEGV in g_type_check_instance_is_a()
I can reproduce this reliably with a fresh install of pidgin on 26.04 by
going to Tools>Preferences>Voice/Video and clicking "Test Audio".
It seems like libpurple is passing garbage into
gst_device_get_device_class. It gets device2 from the "gst-device"
property of a PurpleMediaElementInfo, which is untyped according to GDB,
(gdb) list
2249device2 = g_object_get_data(G_OBJECT(info),
"gst-device");
2250if (device2) {
2251gchar *name2;
2252gchar *device_class2;
2253
2254name2 = gst_device_get_display_name(device2);
2255device_class2 =
gst_device_get_device_class(device2);
2256
2257if (purple_strequal(name, name2) &&
2258purple_strequal(device_class,
device_class2)) {
(gdb) p device2
$14 = 0x642caaf16160
Then GStreamer is crashing due to the type check,
(gdb) up
#1 0x794048632cd8 in purple_media_manager_unregister_gst_device (
manager=0x642caab80af0 [PurpleMediaManager], device=)
at ../../libpurple/mediamanager.c:2254
2254name2 = gst_device_get_display_name(device2);
(gdb) do
#0 0x7940493ff575 in gst_device_get_display_name
(device=device@entry=0x642caaf16160)
at ../gst/gstdevice.c:263
263 g_return_val_if_fail (GST_IS_DEVICE (device), NULL)
So I don't believe this is a GStreamer issue.
