Extracting iso changes target directory's permissions

[Byte Commander]

I have an ISO archive and opened it with file-roller. Then I clicked the big [Extract] button, selected my Desktop as target directory (options "Extract: All files" and "Actions: Keep directory structure" checked) and confirmed. It extracted the files successfully, but also changed the permissions of the target directory itself (to r-xr-xr-x).

This is not expected and not intended. Actually I could no longer create or delete files in my Desktop directory after that, until I fixed the permissions again. I confirmed the behaviour with a different location as well.

Extracting anything into a location should never modify permissions of the target location itself!

If you're interested, here's what I did (extracting to ~/Desktop/testdir ; the "Extract" dialog window can be seen at https://i.stack.imgur.com/rlUvS.png):

$ ls -l Desktop/
total 4
drwxrwxr-x 2 bytecommander bytecommander 4096 Sep 22 21:58 testdir/

$ file-roller test.iso

$ ls -l Desktop/
total 4
dr-xr-xr-x 4 bytecommander bytecommander 4096 Sep 22 16:20 testdir/
