Is this crash reproducible?

Similar crash happened on removing a notification from panel.

Could you install kdebase-workspace-dbg and get a backtrace of the crash from the KDE crash handler?

[Vertago1 (vertago1)]

These are the steps I performed to get the new backtrace (I performed them on a different machine with the same architecture and should have the same packages except I have done updates since then)

I unlocked the widgets:
I added the battery monitor to the panel
I removed the battery monitor from the panel
