Ok, we may have found the issue here. Dolphin uses /tmp by default for 
file copy jobs, and when that fills up, you're sunk, as you've seen :P

However, we've been limiting tmpfs to 800MB, and if we remove that, it 
should allow you to use much more space when doing large transfers. Give 
this a shot, in /etc/rc.conf look for these lines:

# tmpmfs Flags
tmpmfs="YES"
tmpsize="800m"
tmpmfs_flags="-S"
clear_tmp="YES"

Remove the tmpsize= and tmpmfs_flags= lines, and reboot. Then try to 
copy again, does /tmp fill up as quickly and die?
