Inserting USB stick causes udev to enter infinite loop and not display in file manager

[MarkS]

Binary package hint: udev

After insertion of a U3 USB memory stick which should result in the contents being shown in the graphical file manager the display doesn't appear and udev starts taking a large amount of CPU. Attaching strace seems to show that that daemon is looping, log attached. Manually mounting the USB device works fine and the contents can be accessed.

[Herbert Thielen (thielen)]

This looks very similar to Bug #780266 - maybe duplicate?

Herbert,

yes, looks very much like https://bugs.launchpad.net/bugs/780266, didn't come up when apport-bug searched for my report.

Thanks,

Mark.
