libwhiskermenu-related coredump

Hi.
I am not sure it is related to XFCE, but anyway. Please confirm it belongs to some component of XFCE.
It happens a few times a day or so.

I am using XFCE 4.18. I f you need more details, please let me know. Thank you.

It looks like its coming from the Whiskemenu. Which distro, version of xfce4-panel and the whiskermenu are you running? Are they from the repository or something that you built manually?

Edit: also, the symbols are missing. Look at your distro documentation on how to get symbols into the crash dumps so the cause can be investigated. For example, for arch - https://wiki.archlinux.org/title/Debugg … Debuginfod.

distro: 6.1.66-2-MANJARO
xfce4-panel 4.18.5 (Xfce 4.18)
xfce4-popup-whiskermenu 2.8.2

These all are from the distro, I didn't build anything on my own.

We're still not getting the symbols (the parenthesis above should contain information). I'm not sure how Manjaro works with respect to getting debug symbols. Perhaps you can ask at their forum and when you get them, create a bug report against the whiskermenu.

@ToZ
I built xfce4-popup-whiskermenu with DEBUG symbols enabled from the repository and now I have:

xfce4-popup-whiskermenu
libwhiskermenu.so

Is there an easy way to force my XFCE to use this particular version of this plugin? This way I'll be able to examine its segfault. Thank you for your explanations.
