gstyle无法运行，求助！

[windyvictor]

装了个gstyle，但是无法运行，终端输入gstyle出现
Gstyle Config ok
start icons scan
start emerald scan
start metacity scan
start mouse scan
start gtk scan
Traceback (most recent call last):
File "gstyle.py", line 53, in <module>
Gstyle()
File "gstyle.py", line 37, in __init__
self.wallpapers_dict = WallPaperDict()
File "/usr/share/pyshared/gstyle/lib/wallpapers.py", line 58, in __init__
self.scan_system()
File "/usr/share/pyshared/gstyle/lib/wallpapers.py", line 93, in scan_system
wallpapers_global.update(gstyle_wallpapers)
TypeError: 'NoneType' object is not iterable

不知是什么原因，该如何解决？
