Description Kamil Páral 2022-03-22 11:33:20 UTC 
Description of problem:
This crash happens when I want to connect to my public files on a different computer (using dav share enabled through Nautilus and ~/Public folder on a remote Fedora 35 system). I go to  Nautilus to Other Locations, click on "kparal's public files on <hostname>", Nautilus says "Remote peer disconnected" and ABRT shows a new crash notification each time I do this.

Version-Release number of selected component:
gvfs-1.49.90-1.fc36

Comment 12 Kamil Páral 2022-03-22 12:08:49 UTC 
I tested this with several more computers. Connecting F35->F35 webdav using Nautilus works just fine. Connecting F35->F36 also works fine. Only connecting F36->F35 immediately crashes in gvfs. I even found out that you can't connect to *yourself* (i.e. enabling ~/Public sharing and then connecting to your own host from Nautilus -> Other Locations), that also crashes. So it seems the problem is in the connection client being completely broken.

Reproducer:
1. On F36, go to GNOME Settings -> Sharing -> enable File Sharing and the global toggle
2. In Nautilus, go to Other Locations, see your own host under Networks and try to connect to it
3. Alternatively, connect to a different Fedora machine on your local network

Proposing for a blocker discussion, whether remote webdav connection (using GNOME's public sharing system) is considered a basic functionality of Nautilus or not:

Comment 13 Ondrej Holy 2022-03-23 11:02:10 UTC 
Just a note that I can reproduce it and probably see what is wrong, so I am going to propose an upstream fix for it.

A possible duplicate - bug 2062465.
Comment 15 Geoffrey Marr 2022-03-28 19:31:08 UTC 
Discussed during the 2022-03-28 blocker review meeting: [0]

The decision to classify this bug as a "RejectedBlocker (Final)" and an "AcceptedFreezeException (Final)" was made as we agreed this goes beyond 'basic functionality', but does seem worth granting an FE to try and make sure the feature works on the live image.

gvfs-1.50.0-2.fc36 is stable now - it was in https://bodhi.fedoraproject.org/updates/FEDORA-2022-a69718b1e1 - so it should be fixed. Kamil, can you confirm?
Comment 17 Kamil Páral 2022-04-01 07:09:50 UTC 
Yes, it's fixed now.
