So, I can reproduce this, on two systems. There actually seem to be some different variations on the crash, but it always crashes soon after startup, when run as a regular user. It does *not* crash (for Matt Hartley, who pointed this out, or for me, at least) when run as root. The backtraces differ a bit, but always wind up running through the GTK CSS code.

backtrace from one of my crashed attempts
Here's the backtrace from one of my crashes. This is with 2.0.8. I have built 2.1.0 and confirmed that still crashes.
This is the "should not be reached" code we hit in my traceback, from GTK gtk/gtkcssinheritvalue.c :
static void G_GNUC_NORETURN
gtk_css_value_inherit_free (GtkCssValue *value)
{
/* Can only happen if the unique value gets unreffed too often */
g_assert_not_reached ();
}
Here's some references of other projects that ran into this kinda crash: https://github.com/lutris/lutris/issues/5092 https://github.com/bottlesdevs/Bottles/issues/813 https://github.com/haskell-gi/haskell-gi/issues/117 it seems this tends to involve threading and memory management and destructors and other things I'm not any kind of expert on, so I'm not going to attempt a fix for this myself. Upstream report: https://sourceforge.net/p/guvcview/tickets/76/ After further investigation, we suspect this is actually a GTK 3 issue. https://retrace.fedoraproject.org/faf/problems/bthash/?bth=610603e80cf6cdd99354b01975ab1a7b35ad2c50&bth=4a6c303b02b725b8e01f713e3fb4563a476b8e54&bth=c480691445209611ff5079e7be7a2b6a7d488f91&bth=dd80be01d4012f9a2db76faff2f768d77bec4d27&bth=69a7fcaf4179c04257b19a601d9ca079c5c7a803&bth=df920c604a2b926a04a80522743900a4653d85bf seems to be GNOME Connections running into the same thing. Filed https://gitlab.gnome.org/GNOME/gtk/-/issues/6611 . Neal is going to do a build which uses SFML instead of SDL. This seems to avoid the crashes, we think because it forces guvcview to run as an XWayland app (SFML does not have native Wayland support). FEDORA-2024-ac9be9fa7b (guvcview-2.1.0-2.fc40) has been submitted as an update to Fedora 40. https://bodhi.fedoraproject.org/updates/FEDORA-2024-ac9be9fa7b FEDORA-2024-ac9be9fa7b has been pushed to the Fedora 40 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2024-ac9be9fa7b` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2024-ac9be9fa7b See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. I've unlinked this bug from the guvcview update. I think I remember mclasen suggesting somewhere that this may really be a libdecor issue...can't find the reference right now, though. oh, https://gitlab.gnome.org/GNOME/gtk/-/issues/6611 . Asking for clarification there. This message is a reminder that Fedora Linux 39 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 39 on 2024-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '39'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 39 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. This was *effectively* fixed by switching the backend to SFML in https://bodhi.fedoraproject.org/updates/FEDORA-2024-0249d1561b , which makes guvcview an XWayland app and avoids the bug. The underlying problem was reported to libdecor upstream in https://gitlab.freedesktop.org/libdecor/libdecor/-/issues/72 . |
