due to a bug in older boost versions oF will crash when using file operations in oF0.9 and if the locales are not set properly (if LC_ALL is not set)
here a ticket about this issue:
https://svn.boost.org/trac/boost/ticket/4688
i just came across this on a rpi where we have boost in version 1.50 via the package manager (oF require boost 1.49)
in case this affects somebody: to make it work just set LC_ALL like this:export LC_ALL="C"
testing on a ubuntu desktop with boost-filesystem1.55 it works also without LC_ALL being set.
