Look at this:

$ wget --no-check-certificate -c

I managed to download it using a slow connection over 2m 50s, while
the connection was completely uninterrupted.  So the 38s threshold
does not seem true, unless ...

I downloaded this behind a corporate gateway, so I don't know if the
slowness of the connection is only up to my gateway, rather than
between the gateway and the Uni server.


If you prefer to use a proxy anyway, you could set up a SOCKS 5 proxy
connection via ssh to the proxy server in question like so:

ssh -ND 12500 user@proxy_server  (you don't have to use port 12500,
this is just an example)

then either set up the SOCKS 5 proxy in a browser/ftp client and use
that, or use proxychains.  Running:

 proxychains kdeinit4

should allow you to run Krusader to download the file without even
having to restart the Krusader application or set up its proxy
configuration.
