"Window List" has quit unexpectedly & "Show Desktop" has quit unexpectedly

Hello,

I have another bug in my system since a update.
I get this error messages randomly when I switch programs.



Any idea ?

Did you logout-login to reload your desktop?

Hello,

I tried now a logout/login.
It does not change anything.

See if dmesg shows anything (you may keep a terminal open running
Code: [Select]
dmesg -wHT
for continuous and real time printing. Also, check ~/.xsession-errors.

So, it's wnck-applet that crashes. What package it that from? If it's from the AUR, you may need to rebuild it.

wnck-applet is in mate-panel 1.26.2-1
libgtk3 is in gtk 3.24.31-1
I reinstalled both. It takes some time to trigger the error. I will report.
