Your / parition is WAY too small (since it includes your /etc) for an install that is hoping for X windows (KDE is pretty big with all dependencies). If you can, test with one big partition as / and a swap.
My /var partition is quite large because i log ALL traffic in PF (dropped and accepted) and also 3 instances of Snort (per interface including my tun0 just cause) and it gets quite big, my pflog file is over 200mb's and this install was done less than 1 month ago
