auto create the thumbnail of the cahce thumbnail file

SUMMARY

when opening the thumbnail temp directory with dolphin , it will create the
thumbnail of the temp thumbnail files with  a chain of recursion
STEPS TO REPRODUCE
1.  open the  thumbnail temp directory (typically is /tmp) with dolphin
2.  if there isn't any temporary thumbnail file, drop a picture here, if there
is, no steps should be done
3.  wait

OBSERVED RESULT

the dolphin will create the thumbnail of  any picture in this directory,
including the thumbnail cache/temp file itself, the newly created cache/temp
thumbnail file will cause a chain of recursion, making tons of files to create
until I close the window of dolphin

EXPECTED RESULT

do not create any new thumbnail for the cache/temp thumbnail itself in the 
thumbnail temp directory
