[Bug 70008] USB Memory Stick is remounted every 10 seconds

[flix]

Public bug reported:

Using the Edgy LiveCD, I have the following problem with my USB Memory Stick: After plugging it in, Nautilus opens and shows the contents. After 10-30s the "not savely removed"-Window pops up, and the Stick is mounted again ... for the next 30 seconds. Using the same Stick/Cable/Port with installed Dapper works fine.
My Digital Camera is recognized by Edgy as expected: No remounts.

Edgy-LiveCD dmesg says:
