The only time I ran into that problem is when I uploaded a Excel file from a virtual machine. I run VBOX with XP installed, I need the Windows version of office sometimes because some of my company's Visual Basic stuff doesn't run properly on the OSX version of Office. Anyway I noticed that iCoud has a problem with Windows formatted Excel files sometimes. So I rename as a .txt file then upload it, after it's in the cloud I remove the .txt and just add .xls. Hope that helps. One more thing you can try is open up your terminal navigate to the file in question "cd /path to file/", then change permissions by typing "chmod 444 [filename]". I found that sometimes iCloud has a problem excepting certain file types with little permissions or when your home directory is encrypted. i.e. File Vault.
