Comment 13 for bug 482501

Something like this :

mkdir devkit-disks
cd devkit-disks
apt-get source devicekit-disks
wget http://launchpadlibrarian.net/36995686/10-fix-vfat-ntfs-udf-permissions.patch
cp 10-fix-vfat-ntfs-udf-permissions.patch devicekit-disks-007/debian/patches
echo "10-fix-vfat-ntfs-udf-permissions.patch" >> devicekit-disks-007/debian/patches/series
cd devicekit-disks-007
dch -l custom "Mount permissions fix."
dpkg-buildpackage -b -us -uc -rfakeroot
dpkg -i ../devicekit-disks_007-2ubuntu4custom1_amd64.deb

If you don't have some programs required for this sequence install them. Last command will install the package, package name is for amd64 architecture, substitute it if you have another one.
