[Bug 1814088] Re: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal]
Confirmed, but the number of crash reports is incredibly low right now: artful = 1 bionic = 1 cosmic = 1 disco = 1 Also it sounds like a memory corruption issue. So the location it crashed in may not be the problem at all. If you are able to ever reproduce the issue then please try adding this to your /etc/environment first: MALLOC_CHECK_=3 Then produce the same crash and that should give a better idea of the root cause. ** Changed in: totem (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1814088 Title: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1814088/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

This just came up out of the blue. Maybe a video embedded in Tweetdeck tried to trigger it? (Firefox 66.0b4 from firefox-next ppa, installed for the working CSD when buttons on left.)

Re: [Bug 1814088] Re: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal]
True. And I can confirm it's not listed in my plugins at all. (There's just Cisco OpenH264 and Widevine). Only potentially-relevant extension is Disable HTML5 Autoplay, which if anything should *stop* any video being played before it gets to the software that does it. Only other thing that seems odd, is the mimetime mapping Firefox has for MP3 audio (in prefs) *defaults* to Videos, but in my case it's set to "Use env"... but I wouldn't have set that (is first time I've seen it). It wouldn't be surprising if "Use env" gets it to be sent to Videos too, by a system default? So maybe it was an MP3 file. But not one I knowingly clicked on. ... but finding some MP3 files and playing them in the browser deliberately is working fine. So no, I'm sorry, I'm mystified. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1814088 Title: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1814088/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Thanks for the reply. It's a bit weird if it comes from firefox because the totem webbrowser plugin got deprecated and there is no reason firefox would call to totem to play video... -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1814088 Title: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1814088/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
Re: [Bug 1814088] Re: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal]
I agree it's a bit of a nightmare. It was the start of the day and I literally just had Firefox-Next open, and Slack (using the app, not via Firefox). No video had been posted to slack. I can only think some random embedded video went by on the timeline or activities column in tweetdeck (the only tab) on firefox. Nothing else was going on, and said embedded videos usually either work fine or not at all. In the past I've had stuff like this happen when opening a Nautilus window onto a directory with videos in it, so it being the preview of said videos that probably crashed... but not this time. So I agree, there's probably not much to be done about this unless it starts happening more. So far just that one time. (I didn't set it to ignore similar in future.)

Thank you for your bug report. Without steps to reproduce the issue it's going to be a bit difficult to debug that though, could see if you can trigger it again by doing the same things you were doing? ** Changed in: totem (Ubuntu) Importance: Medium => Low ** Changed in: totem (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1814088 Title: totem crashed with SIGSEGV in tcache_get() [assertion "nqueue != NULL" failed in g_object_new_internal] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1814088/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
