Modern distributions have the sbin directories on the end so users will expect them to be present for ThinLinc sessions as well.
This is $PATH on Ubuntu 14.04: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/thinlinc/bin And on Fedora 20: /usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/opt/thinlinc/bin:/home/tluser/.local/bin:/home/tluser/bin I think the Fedora approach of putting /sbin after /bin is safer, so let's go with that.
Fixed in r28879.
Verified using build 4332, PATH contains paths to sbin after bin...
