Description of the Bug:

I´ve got an email from a user. The upload via the three points is working. But she has problems when downloading one or more files using the grey download button. This only happens for pdf (blank pages), zip (blank folder) and docx, pptx, xlxs (Error; s. below). It does not happen for csv, json and txt
