Well, you can go to /proc/$PID_OF_PROCESSING_OPENING_THE_FILE/fd/
do an ls -la, identify the fd of the file deleted but still open and do a cp $FD ~/my_deleted_file
Example:
[japc@morgoth:/proc/3743/fd]$ ls -al total 4 dr-x------ 2 japc japc 0 Oct 7 15:25 . dr-xr-xr-x 4 japc japc 0 Oct 7 15:23 .. lr-x------ 1 japc japc 64 Oct 7 15:25 0 -> /dev/null l-wx------ 1 japc japc 64 Oct 7 15:25 1 -> /home/japc/.xsession-errors l-wx------ 1 japc japc 64 Oct 7 15:25 2 -> /home/japc/.xsession-errors lr-x------ 1 japc japc 64 Oct 7 15:25 255 -> /usr/bin/startkde [japc@morgoth:/proc/3743/fd]$ cp 255 ~/startkde
