listObjects: Marker should be unescaped before being used internally.

Browse Source 
Without this change listObjects() goes into an infinite loop for
files which have special characters i.e "++" encoded with "%2B%2B".

We have to unescape and convert them to their native representation
before being used internally.

Fixes #1052
