the result of revdeletefolder = 1?

[Tiemo Hollmann TB]

Hello,

I am trying to delete one of my apps on OS X 10.9.5 with revDeleteFolder.

I get "1" as the result and the app isn't deleted, though I have read &
write permission on it. With other apps in the same folder it worked as
expected. Can anybody tell me, what the result "1" means? And how to
workaround?

Thanks

Tiemo
