[Pkg-utopia-maintainers] Bug#563892: devicekit-disks: segfault in devkit-disks-daemon on USB stick removal

[Daniel Kahn Gillmor]

Package: devicekit-disks
Version: 009-2
Severity: normal

a 1GB USB stick on this testing/unstable system was inserted, mounted,
read from, unmounted, and removed.

devkit-disks-daemon appears to have segfaulted upon device removal.

dmesg tells the story:

(note that it looks like the usb stick has some oddities in its
formatting.  it's a 1GB disk, but the first partition appears to
believe it is longer than 1GB.  Why?  not sure.  i can get you a dump
of the partition table on the USB stick if that would be helpful in
replicating the problem.

Thanks for maintaining devicekit-disks in debian.
