Bug ID: 107058
Summary: [Wayland] plasmashell gets SIGSEGV after clicking on
Application Menu for second time
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/i965
Assignee: intel-3d-bugs at lists.freedesktop.org

Hi,
I submitted the following bug report to the developers of KDE Plasma:
https://bugs.kde.org/show_bug.cgi?id=395753
However, we got to the conclusion that this is a Mesa bug instead. Thus, I will
just summarize what I wrote there.
First of all, my hardware is an Intel i3-3110M CPU, which comes with a Intel HD
Graphics 4000 GPU.
The versions of some of the software I have suffered this crash with are:
* Arch Linux x86_64
* Plasma 5.13.0, 5.13.1 or 5.13.2
* Qt 5.11.1
* Mesa 18.1.1 or git-103087.ab2643e4b0 (from the unnoficial mesa-git
repository: https://pkgbuild.com/~lcarlier/mesa-git/)
The steps I followed are these:
0. Start a Plasma 5 Wayland session (if you are in tty, run
"startplasmacompositor"). There is no such crash in the usual X session.
1. Click with the mouse on the Application Manager icon, so that the
Application Manager appears.
2. Click again, so that it hids.
3. Click again, in an attempt to make it appear again.
However, the screen and keyboard freeze instead. The only way to get full
control over the computer again, other than rebooting, is unrawing the keyboard
(Alt+SysRq+R), changing to another tty and killing kwin_wayland, because "The
X11 connection broke" (according to the messages in stderr).
It has to be noted that the Application Manager is not the only applet from the
panel that suffers from this crash.
So here's a backtrace of the process that gets SIGSEGV, using Plasma 5.13.2 and
mesa-git-103087.ab2643e4b0

This is another backtrace using Plasma 5.13.1 and Mesa 18.1.1, but without
debug symbols:

Please do not hesitate to ask me for any other information you need. This is my
first time submitting a Mesa bug and I might not be foreseeing all the
necessary information.
Thanks.
