I am using sid already and there're no new versions of udev available
other than 0.141-1 ...

There're also no new version of lockfile-progs other than 0.1.13 ... I
tried with usbmount 0.0.14-1 which I found in svn and the disk is
mounted fine:

I believe that 0.0.14-1 seem to work fine, since it doesn't try to lock
(or doesn't show it); with this there is a difference of +/- 5 seconds
between the two mounts, while 0.0.17 does it at the "same" second.
Unfortunately I don't have enough time left (yet) to go deeper in this
and check it; for now I'll pin usbmount to 0.0.14-1 ...
