Actually, even that can get you in to trouble.  If you want to be
robust, consider using a delimiter that *can't* be in the filename.  For
example, the NUL byte:

SAVE_IFS="$IFS"
IFS=$'\0'  # temporarily change how bash delimits information

# now do your business as usual.  Note there's now no need to quote $f
locate -0 *.ods | while read f; do unzip -p $f | \
  grep -i "gas" > /dev/null && echo $f; done

IFS="$SAVE_IFS" # restore normal bash delimiters

* untested, off the top of my head, beware, etc.
