Does the issue reproduce without any extensions enabled?

Hello. I helped with collecting information for the upstream bug. This issue impacts a clean, completely-updated Fedora 32 (beta) install.

Hello, apparently this crash occurs when I/O operations are being performed and you open the application drawer. For example: you install a package with dnf and open the app drawer, gnome-shell crashes. You update a Flatpak app and open the app drawer, gnome-shell crashes. You open several programs almost at once and you open the app drawer, gnome-shell crashes.

At least that is what I have been able to observe after experiencing this bug multiple times, I hope it helps.

For anyone who can reproduce this bug at will, could you install the following two scratch builds, reproduce the issue, then attach:

1. The full backtrace of the crash (using "coredumpctl gdb" and "bt full")
2. The output of "journalctl _PID=<pid> > gnome-shell-debug.log" where "<pid>" is replaced with the pid of the crashed process (as logged by coredumpctl).

Note that the result of 2. might be very large. Afterwards, I'd recommend downgrading to the gnome-shell and mutter packages from Fedora proper, as the linked builds produce a lot of debug output.

Proposed as a Blocker for 32-final by Fedora user jadahl using the blocker tracking app because:

 This bug is the most reoccurring full desktop crash we're seeing at the moment in F32. Upstream is on track to hopefully have this issue resolved shortly.

It has been happening unreliably for most, though reliably for some by simply opening the "Show Applications" view. It does not require any extensions to be reliably reproduced.

A scratch build with a potential fix available here: https://koji.fedoraproject.org/koji/taskinfo?taskID=42872652

Discussed during the 2020-03-30 blocker review meeting: [0]

The decision to classify this bug as an "AcceptedBlocker" was made as it violates the following criterion:

"All elements of the default panel (or equivalent) configuration in all release-blocking desktops must function correctly in typical use" with reference also to "All known bugs that can cause corruption of user data must be fixed or documented at Common F32 bugs" (as Shell crashes can often cause data loss).

gnome-shell-3.36.1-2.fc32 was part of the 3.36.1 megaupdate: https://bodhi.fedoraproject.org/updates/FEDORA-2020-ed25e0cdcb (already in stable).

I'll move it to ON_QA as I haven't seen anyone confirm the fix. Please test gnome-shell-3.36.1-2.fc32 if you were affected by this, thanks!

FAF does show occurrences down significantly over the last few days, which tracks:

https://retrace.fedoraproject.org/faf/reports/2847765/

positive confirmation would be good though.

I'm using and testing the gnome-shell-3.36.1-2.fc32 version, and so far I haven't had any breaks or freezes and everything is working perfectly.

No crash since upgrading to gnome-shell-3.36.1-2.fc32.

OK, so let's call this fixed. If anyone still hits it with the mega-update, please reopen. (FAF data continues to be down over the last few days).
