Contact downloads the file (can repro, always the same sha256sum!)

Uploads from Conversations work fine.

I'm uploading APKs daily, this is the first time one become un-installable, not sure others were affected.

Amended title

Sending the same file w/ OMEMO but with .ZIP added to the name:

<iq id='b5811c89-1431-45ba-b5ec-c9e80fcd5a61' type='get' to='upload.mydomain.tld'>
  <request xmlns='urn:xmpp:http:upload:0' filename='org.woheller69.whobird_15.apk.ZIP' size='17228316' content-type='application/octet-stream' />
</iq>

...file size is correct (+16 from OMEMO)
