Universes or dev image problem?

In squeak-dev-beta-123 image if I load Seaside from the Package Universe
Browser I get a walkback when trying to load

'KomServices-gk.3.mcz'

The walkback is 'Error: file is too short' and, on inspecting the file
it simply contains the text:

server aborted early

I'm not sure if this is an issue with the Universe config, the dev image
or simply a temporary failure downloading this file.

It's working fine now...must have been a temporary problem with that server.

It's the last, but there is a bug here, too.

The difficulty is that HTTP download errors are reported in a strange
way. The core method returns a string instead of a MIMEDocument.
Then, the URL code converts the error message to a MIMEDocument that
starts with the text "error".

Errors should be reported better. One refactoring would be to make an
"ErrorResult" subclass of MIMEDocument. Then, the HTTP code could
robustly track which downloads are errors, without breaking
compatibility with code that simply displays the result whether it was
an error or not (e.g., Scamper).

I've posted this issue on Mantis:

http://bugs.squeak.org/view.php?id=6495

I won't do it today; anyone should feel free to beat me to it!

Is it related to this issue ?
http://bugs.squeak.org/view.php?id=5200
I reverted the method to a earlier version and got it to work.
I think the failing method version was made to make proxies work but I'm
not sure.

It does not sound like the same thing. There is an ongoing problem
with temporary failures, e.g. if the server gets overloaded. Right
now the errors are not reported in a robust way. It is easy for an
error result to be mistakenly treated as a successful download.
