-- Information about the crash:
I logged into Plasma 6.0.2 on Wayland in a Fedora 40 KDE Plasma installation. I
was troubleshooting a kwalletd6 crash when starting the Proton VPN GUI which I
reported at https://bugs.kde.org/show_bug.cgi?id=482819 The problem involved
qca 2.3.8. I built qca 2.3.8 with a patch by Albert Astals Cid
https://bugs.kde.org/show_bug.cgi?id=482819#c11 I upgraded to the qca 2.3.8
build with the patch. I logged out of Plasma and logged in again. I ran the
following steps described by Albert to run kwalletd6 under valgrind then run
the Proton VPN GUI to reproduce the crash
https://bugs.kde.org/show_bug.cgi?id=482819#c9
"Open a terminal
Start kwalletmanager5 and press the close wallet button (force if needed)
killall kwalletd6 (run it twice to make sure it has not re-spawned itself)
valgrind kwalletd6
Now in another terminal
kwalletmanager5 and press the open open wallet button
protonvpn-app"
The panel disappeared and reappeared automatically right after I ran
protonvpn-app in Konsole. A plasmashell crash notification was shown.
plasmashell crashed in dri2_invalidate_drawable in the radeonsi driver in mesa
24.0.0. The argument dPriv was null in dri2_invalidate_drawable which might've
led to the crash. The crashing line ../src/gallium/frontends/dri/dri2.c:99 was
drawable->lastStamp++; in the following
static void
dri2_invalidate_drawable(__DRIdrawable *dPriv)
{
struct dri_drawable *drawable = dri_drawable(dPriv);
drawable->lastStamp++;
This problem didn't happen before when I ran the Proton VPN GUI.
The reporter is unsure if this crash is reproducible.
