failed to run shell script

[seagrb]

hi there,

i want to rename the created sparseimage via the following script:

tell application "Finder"
activate
set name of document file "test.sparseimage" of disk "BACKUP" to "test1234.sparseimage"
end tell

unfortunately i get the error message "failed to run shell script rename.scpt"

the error log tells me:

...
| 10:17:42 AM | Info | ...ACTION: Restoring Spotlight state on test
| 10:17:42 AM | Info | ......COMMAND => Restoring Spotlight search indexing state on test
| 10:17:42 AM | Info | ...ACTION: Running shell script rename test.scpt

| 10:17:42 AM | Error | sh: /Volumes/BACKUP/rename test.scpt: cannot execute binary file

what am i doing wrong?
