udisks-daemon consumes far too much CPU and RAM

[teledyn]

The usb-creator-gtk process causes system load to shoot to 10 (only app running); top shows udisks-daemon CPU at 40% and several gigabytes of swap space taken (causing excessive thrashing). Eventually the process aborts with apport responding that it has insufficient memory to file a report.
