Re: xfce4-panel coredump

Thanks @varnie, unfortunately nothing special in this config that tells me anything (I tried to add a workspace switcher just in case...)
Did you try to downgrade libwnck3 to 43.0-2 like in the thread linked by @ToZ to see it that fixes the issue?

Re: xfce4-panel coredump

No problem
I've downgraded libwnck3, but it didn't solve the issue:

[varnie@heimdal ~]$ pacman -Qs libwnck3
local/libwnck3 43.0-2

i.e. after that I still experience crashes (that case with closing of the LMMS app).

Re: xfce4-panel coredump

Ok thanks, could you also try to downgrade glib2 to 2.74.6-1? (I don't know if you follow the thread on the Arch forum)

Re: xfce4-panel coredump

I'm sorry, but the specified version of glib2 is not available. However, here is a list of all the available versions:

glib2 2.74.4,
glib2 2.74.5,
glib2 2.76.1 (installed)

When I tried to use the 'downgrade glib2' command to switch to glib2 2.74.5, it worked without any problems. However, I started experiencing various issues after the switch. For example, Firefox became unstable, and Geany refused to start, displaying the following error message:

/usr/lib/libtracker-sparql-3.0.so.0: undefined symbol: g_task_set_static_name

Meanwhile, I had to revert the switch back.

Re: xfce4-panel coredump

Argh, there are already things that depend on version 2.76 (probably optionally, but since they were built against it, the binary depends on it).
Also tracker3 is a dependency of gtk3, so it can't be avoided.
It would be really nice if you could try downgrading again to see if you can still reproduce the panel issue, though.
But I could understand if you don't want to put your system at risk.
The idea would be to also downgrade tracker3 to version 3.4.2, i.e. before the switch to glib2 2.76.0 which took place on March 10th.
It's up to you

Re: xfce4-panel coredump

Oh also, don't forget to restart the panel after downgrading to test (same for libwnck3 before, just in case).

Re: xfce4-panel coredump

Should be fixed in https://gitlab.xfce.org/xfce/xfce4-pane … 9dbde04ea0
Backported to 4.18 as https://gitlab.xfce.org/xfce/xfce4-pane … 50d5a607c3
We had to use Valgrind to get to the bottom of this! https://gitlab.xfce.org/xfce/xfce4-pane … note_69718
I don't know yet when 4.18.4 will be released though. Thanks to all for your help
