Applescript application hangs on 10.9 when executi

Question

I'm executing the following line in an Applescript application.

set POSIX_path to "/Applications/iPhoto.app"
do shell script "sudo rm -rfv " & quoted form of POSIX_path with administrator privileges

The authentification screen pops up as it should but after authenticating the application just freezes upon executing this command. This problems only occurs in 10.9.

When I set the permissions of the folder to be delete to "everyone can read & write" it works.

Does anyone have a clue what has been changed?

EDIT: When I repeat the execution of this script by checking du -shx /Applications/iMovie.app it manages to delete a few more files with every try.

$ open compiled-applescript.app/
$ du -shx /Applications/iMovie.app
1.4G    /Applications/iMovie.app
-- force quit AppleScript --
$ open compiled-applescript.app/
$ du -shx /Applications/iMovie.app
1.3G    /Applications/iMovie.app
-- force quit AppleScript --
$ open compiled-applescript.app/
$ du -shx /Applications/iMovie.app
1.0G    /Applications/iMovie.app

Answer 1

After days of trying everything to sort out this problem I finally found what was causing this issue.

It's the verbose-option (-v) of the rm-command. Leaving it out makes the application work flawless again. Maybe Apple accidently introduced a buffer overflow. I will report this under the problem ID 15309626 I created at Apple's bugtracker. Maybe they'll fix it until the first 10.10 DP :D

Its working fine on OS X 10.9 (13A603)

set POSIX_path to "/Users/paragbafna/Desktop/untitled folder"
do shell script "sudo rm -rfv " & quoted form of POSIX_path with administrator privileges

Does anyone have a clue what has been changed?

Well yes.. Gatekeeper has changed, that may be the cause..

When I set the permissions of the folder to be delete to "everyone can read & write" it works.

Did you do this from Finder or from the command line with chmod 0777? The latter may delete some attributes that Finder does not remove.

What setting is selected here, on your computer?

If you have a restrictive setting, try "Anywhere" to see if it solves the problem. If this is the cause you may:

1. Have custom command line tools installed, (e.g. MacPorts) or something you compiled yourself (since this is happening on 3 but not all computers and obviously you are not a "generic" user).
2. Your applescript is not being trusted, you can try signing it if possible, otherwise this may work:

   If the user wants to run an application blocked by Gatekeeper, they have several options. Gatekeeper could, in effect, be turned off by letting it run all applications. A power user may opt to remove the quarantine attribute or use the spctl command to add a new policy in the security assessment policy subsystem. - TrendMicro - about Gatekeeper

3. Last resort idea.. Check your disk permissions, re-install Xcode if you use that, maybe the signatures are corrupted.
4. Write a shell script instead, I don't know if it is just about deleting a few files, then you can definitely do it in shell script, or comment to let me know what you're trying to achieve.
