Nautilus 46.0 Properties window indefinitely freezes/crashes for certain files

Applications

Greetings, this is my first time posting to Discourse. I wanted to ask about a possible bug, since I do not yet know how to gather useful information/output for a report, and I understand that accidentally cluttering the tracker would not be helpful on my part. Searching the Nautilus/GLib GitLab trackers and Red Hat’s Bugzilla over the past few days did not reveal anything relevant.

When I open a Properties window for any file in Nautilus 46 (46.0, 46.rc) there is a significant chance that Nautilus will become unresponsive forever, entering an inescapable loop. I must then wait for the “unresponsive application” modal from Mutter, or else end the process myself. I have tried waiting for the process extensively, even lengthening the “unresponsive” modal timeout to 5 minutes with gsettings. Some audio/video files can reliably freeze Nautilus after opening Properties only 1-2 times, never needing more than that. I am not using extensions/plugins to Nautilus nor gnome-shell itself, and have tried setting environment variables to ensure this, but observed no changes.

I first encountered the freeze on Arch Linux with Nautilus 46.0, and assumed it was specific to my use case, or something unsupported I had unknowingly done. However, when I test the official live media of Fedora 40 Workstation Beta, open Nautilus, and view properties of the same files on local storage, the same freeze quickly happens on any computer.

If anyone can replicate this or point me to relevant information about it, I would be extremely grateful. Unconditionally, thank you for your time.

Hi! This sounds like a serious bug, thanks for reporting it. You’re more than welcome to open an issue in Gitlab for it. It would be best if you can also provide a stacktrace of nautilus in a hanging state, by running it in gdb and stop the process while it’s hanging. You can check the handbook for more info on how to do that.

I’m able to reliably reproduce it on Arch Linux with Nautilus 46.0 with any of my MP3 files. Also with the MP3 files from Sample MP3 audio files.

Opening Properties for a MP3 file once, twice sometimes three times causes Nautilus to become unresponsive and needs to be killed to get out of it.

The files are on my root filesystem which is ext4 formatted. But I copied a MP3 file to /tmp which is a tmpfs and opening Properties for the file there also cause the issue.

Thank you for the handbook link. It looks like the example uses a process that has already segfaulted and dumped core, but adapting for a hanging process like you said was straightforward. (I have used gdb before, albeit in much smaller projects.)

The bt full output is fairly long, so I hope it is okay to post it here to ensure that anything captured is actually correct/helpful. As new users cannot use attachments, I will need to use a collapsible Details block, so hopefully this is not considered spam.

Thanks, that stacktrace looks good, but it seems there is a deadlock situation, meaning the thread you observed in the stacktrace is blocked by another one. Can you do the same thing and run thread apply all bt full instead?

Putting the stacktrace in a collapsible section would be perfect for Gitlab too :slight_smile:

Thanks again for stepping me through this process, and for the commits/MR to resolve the bug. I forgot to post an update acknowledging this, but for anyone who finds this thread, I did properly report the issue on GitLab.

Since I am not doing production work on my Arch install, I have downloaded the MR changes as a .patch and modified Arch’s official build script for Nautilus to apply it. As a stopgap solution until the next official release, it’s been working great.
