task udisks-daemon:1825 blocked for more than 120 seconds.

Binary package hint: udisks

I have a usb memory key device with 2 GB, probably with broken sectors. I try plugged, and appear a window of nautilus with the files, but I can't remove, format the partition or copy files. Just see and open some.

I assumed that my usb memory key is broken, but searching on dmesg I found this crash, maybe it is usefull for fix some errors or procedeed on a better way, or display a useful message for the destop users (for example, usb memory key damage, bad sectors found):
