Description Debarshi Ray 2017-09-13 06:57:44 PDT
I don't know if this is Mesa or WebKit, so I'll take a random guess start with WebKit.


I am running the GNOME Wayland session on Fedora 26 x86_64. The machine is a ThinkPad x1 Carbon (2nd gen.) with Haswell Mobile graphics. I have:

control-center-3.24.3-1.fc26.x86_64
gnome-online-accounts-3.24.2-1.fc26.x86_64

webkitgtk4-2.16.6-1.fc26.x86_64

Steps to reproduce:

(a) Revoke GNOME's access to your Facebook account (if any). Go to www.facebook.com -> Settings -> Apps. Hover over GNOME, if it's there, click the x button, followed by remove.

(b) Delete any cookies help by GOA at ~/.cache/goa-1.0/ [1]

(c) In GNOME, go to Settings -> Online Accounts.

(d) Remove any existing Facebook account. Close the undo notification to ensure that the account is really gone.

(e) Try to add a new Facebook account. Since you revoked GNOME access in (a), you'll have to click through a few more pages than usual.

(f) gnome-control-center crashes right after the final "ok".



This doesn't happen in the X session. It also doesn't happen if you skip (a).

Comment 2 Adrian Perez 2018-05-02 14:39:14 PDT
Is this still happening with WebKitGTK+ 2.20.1? It would be great
if you could check it. Thanks!
Comment 3 Michael Catanzaro 2018-05-21 18:22:29 PDT
This is *really* deep inside mesa, rishi. I'm going to say not our bug. In the off chance the mesa developers think it's not them, then it should go to the GTK+  developers since there isn't even any WebKit function anywhere on the crashing thread.
