Hi all, I recently ran into the problem with a server returning text/plain instead of application/octet stream again (see http://lists.gforge.inria.fr/pipermail/pharo-project/2012-April/062388.html), but the resulting error (a MNU for Character>>bitOr:) failed to job my memory as to the actual cause. Is there any chance the final line of McHttpRepository>>readStreamForFileNamed:do: could be changed from: ^ aBlock value: contents readStream to: ^ aBlock value: contents asByteArray readStream I know that it would be best if Web Servers never served up binary content as text/plain - but it's not always in the power of someone who encounters this error to fix that. Failing that, the condition should probably be explicitly checked for and a more useful error message given, as the cause is far enough away from the symptom that it takes a bit of digging to find out what went wrong. Regards, Stuart
