I just got something similar:
root      2930  0.0  0.0  42044    84 ?        R    Jan16   5:38 devkit-disks-daemon: polling /dev/hda /dev/sdb
$ ls -l /dev/sd*
brw-rw---- 1 root disk 8, 0 Jan 16 08:42 /dev/sda
brw-rw---- 1 root disk 8, 1 Jan 16 08:42 /dev/sda1

A pretty pointless backtrace without debugging symbols:
0x00007f893766c2b0 in g_list_length () from /lib/libglib-2.0.so.0
