Any difference is important, sometimes you can find there HTML code from some
proxy or server which generates HTML page instead of 404 or someone
trying to sell you domain of long dead project etc

OK, I was asking mostly because newer bitbake (1.19+ is new enough)
renames file with bad checksum, moving corrupted download aside so it
doesn't stand in way for new one.

Check log.do_fetch in WORKDIR/temp, I'm not sure if the error shows only
the original URL or also possible (PRE)MIRROR url from which it could
download that empty file.

You should see the exact URL in log.do_fetch.

You can also check for (PRE)MIRROR usage in bitbake -e tslib output
