Neat no?  :-)

I initially tested it in a VM but somehow ‘gsd-housekeeping’ doesn’t
trigger low disk space notification in VMs.  So I reconfigured a
victim’s actual laptop, filled the disk, and waited for the
notification.  (Worry not, I have since freed disk space and the victim
now has the status of happy user.)

Is there a way we could get the message of that button translated?
Or is the only way to do that to submit the patch upstream?
