[mono-cecil] "Object reference not set to an instance of an object" error when saving assembly

[Wicky]

Hi, Jb,

When I loaded and then saved this assembly without any change, error
occued:
http://www.fileden.com/files/2008/8/5/2035756/Test/WindowsFormsApplication1_bug.zip

Error information:
Object reference not set to an instance of an object.

It seems the binary puts resource into .reloc section, but this
section is ignored by Cecil,
in ImageRead.cs line 279:

if (section.Name == ".reloc")
     continue;

Is this designed or bug?

Regards
Wicky
