Public bug reported:

Binary package hint: compiz

This crash occurs every time that I click on the battery icon on the
panel and then click on"Laptop battery estimating..." in order to check
the battery data. After clicking on "laptop battery estimating..." the
launcher freezes completely, but the dash button still usable.
