Hello Ludovic,
I tried to collect some more information from your crash dump.
With debug symbols this backtrace should look like below.
I guess you are running a nvidia graphics card
with the nouveau drivers?
As a workaround it may work if you start the client
from a terminal by following:
export LIBGL_ALWAYS_SOFTWARE=1
nextcloud
Or maybe this:
export QT_XCB_FORCE_SOFTWARE_OPENGL=1
nextcloud
Maybe you can confirm my findings, and forward the output of
following commands to this bug:
lspci | grep VGA
glxinfo | grep -i -E "GLX_MESA_query_renderer.:" -A5
Kind regards,
Bernhard
