Encode any ":", "@" or "/" within the user and password field in proxy settings.

[Igor Korobka]

I have password for corporate proxy server and this password contains following symbols: "_%/&{" (without quots). One of the mentioned symbols in password is not escaped (I think this is "/" symbol). So, when I try to use Internet connection through corporate proxy I gets some every weird messages. I've attached video where you can view these messages. The same issue appears in Synaptic package manager. I can't provide report of the ubuntu-bug tool because it fails to upload report through proxy.

Here are some info that ubuntu-bug collected on my desktop:

Confirm this issue. Same times difficult passwords (with a lot of escape symbols) not works in GNOME.
Seems escape password issue.

Thanks for your report.

According to the specs (http://www.w3.org/Addressing/rfc1738.txt) some symbols need to be escaped in username and password fields:
'The user name (and password), if present, are followed by a commercial at-sign "@". Within the user and password field, any ":", "@", or "/" must be encoded.'

As a side note the specs also mentioned that the scheme http://<user>:<password>@<host>:<port>/ is not valid, but most apps (apt, wget, ...) accepts it and this behavior is documented in the apt.conf man page for example.

Setting status to triaged.
