Segmentation fault in Ubuntu 20.04 Daily, in Wayland session

[Simos Xenitellis ]

I installed Ubuntu 20.04 daily (15-Mar-2020) in a QEMU/KVM VM.
I logged on using the Ubuntu Wayland environment (somehow "Ubuntu" would crash and not log me in).

I was prompted in Software to update Snap Store, which I did (did not try Snap Store yet).
When I then try to run Snap Store, I get a Segmentation fault. See attached file for the snap-debug output.

I tried again and cannot reproduce.
I am closing this.

for posterity: I got the error when installing 20.04-daily from a special USB stick, where you just copy the ISO on there, and have grub perform the booting of the ISO. I got other weird behaviour, like on the GDM screen there was an option to login with Wayland which worked, but "Ubuntu" did not work (when you tried to log in, it would flash and return back to GDM).

Still open with today's snap store update (336) using stable/ubuntu-20.04 channel.

[Francois Thirioux (fthx)]

snap-store (336) is ok with gnome-3-34-1804 version 24.

[Francois Thirioux (fthx)]

Additonally, I noticed that font rendering/spacing is bad in Wayland only. I don't know if it's related at all...

I updated the title to mention the Wayland session.

[Francois Thirioux (fthx)]

Solved today for me, because of v. 24 of gnome-3-34 in stable/ubuntu-20.04 channel.

Wayland users : do you experience bad fonts spacing ? Not happens in X11 for me. Just to know if I open another bug.
