Image filename

[GoogleCodeExporter]

PROBLEM:
I made an image that has filename contains plus(+) character.
When I validate epubfile that use the image, a validator says "WARING" and 
"ERROR".It says "Filename contains spaces." but I didn't use spaces when I 
named the image.Which cause this error, the validator or the image? Thanks for 
your help.

METHOD:

What steps will reproduce the problem?
1.Make image that has filename contains +.
2.Make xhtml that use the image.
3.Validate the file.

RESULT:
following epubcheck error message
WARNING: h_no_test.epub/OEBPS/image/ec_000000_png_gaiji_min_u 34db.png: 
Filename contains spaces. Consider changing filename such that URI escaping is 
not necessary
ERROR: h_no_test.epub: image file OEBPS/image/ec_000000_png_gaiji_min_u 
34db.png is missing
WARNING: h_no_test.epub:item(OEBPS/image/ec_000000_png_gaiji_min_u+34db.png) 
exists in the zip file, but is not declared in the OPF file

EXPECTED:
I think that the validator changed the image filename from 
[ec_000000_png_gaiji_min_u+34db.png] to [ec_000000_png_gaiji_min_u 34db.png].
It changed plus(+) to space( ).

PLATFORM:
epubcheck-3.0b5
Windows 7 64bit
java version "1.7.0_04"
