From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
When using wget to fetch file over ftp connection and there's a semi intelligent firewall in between wget crashes.

Version-Release number of selected component (if applicable):

How reproducible:
Always

Steps to Reproduce:
NOTE: there must be a firewall spurting fancy responses to see this behaviour.

Comment 2 Roberto Pallucchini 2005-08-04 07:53:19 UTC 
can you tell me another site that i can reproduce this error?
i have tryed people.redhat.com but it work correctly with my system. Do you pass
throught a firewall or other to access internet?

regards
Roberto
