Filenames with spaces

I'm able to open and save files with filenames without spaces. eg. Untitled1.odt

If there is a space in the filename like Untitled 1.odt, I save it in my database as Untitled 1.odt. And this is the filename I send to zoho. The file opens perfectly, but I get an error while saving it back.

This is what my nginx logs show for such POSTs from zoho:

72.5.230.65 https <my domain name> "/save_file" [14/Oct/2010:17:10:07 -0400] - 302 0 "POST /save_file HTTP/1.1" "Apache-HttpClient/4.0.1 (java 1.5)"

Any ideas what am I doing wrong here?
