Thanks for testing!

That's unrelated. Due to this bug, the drive wouldn't have been
automounted in the first place.

Yes, unfortuantely the right-click menu is an UI disaster in Karmic.
"Unmount" disables just a single partition, but leaves the device
fully powered, so that you can remount it. "Eject" disables all
partitions and disconnects power from the device, so that e. g. iPods
stop whining about "unsafe to disconnect". "Safe eject" additionally
disconnects power from the entire USB controller, which is necessary
for some hardware. However, this breaks for builtin USB controllers,
so it could not become the default yet (a possible solution is being
discussed upstream).
