As a workaround I downloaded filetypes seperately.

downloading sheets with extension ods produces the same error. Extension pdf is 
a workaround.

I believe this is because the check for an invalid file name was before the 
construction of the export file name. I 
have fixed this in the currently subversion commit and this will make it to 
beta2.
