Comment 13 Bastien Nocera 2023-01-11 14:59:18 UTC 
I don't know how it happens, but this line is making epiphany crash:
portal->sender = g_strdup (g_dbus_connection_get_unique_name (portal->bus) + 1);

The only way this crash is if the bus isn't set, and the unique name is NULL. The upstream code has changed a bit, and will now show an error and assert if there's a problem with D-Bus.

Can you reproduce the problem, or did this only happen once?

If it happens repeatedly, I can cherry-pick parts of upstream commit c4735251029f1a30c41f6d0ea37f245bef270445 so we see what the D-Bus error is. Otherwise I'll just leave it until there's a new upstream version of libportal to rebase.

You used gnome-timeshift which uses epiphany.
Comment 16 sime.thompson 2023-01-17 15:20:07 UTC 
thanks...as I now remember, Timeshift worked perfectly using both rsync and btrfs then it just crashed when it finished. The backups/snapshots were perfect.

My question was: Can you reproduce the problem, or did this only happen once?
Comment 18 sime.thompson 2023-01-17 16:01:36 UTC 
I tried it a few times...same result each time. There wasn't one time when it didn't crash on completion of backup.
Comment 19 Bastien Nocera 2023-01-18 10:28:12 UTC 
Can you please update to the version of libportal built here, and test this again?

This should give a slightly different output if the problem still happens.
