Dear Maintainer,

It seems that Thunar does not properly handle URLs to remote resources
that use an IPv6 address for the host.

When I try to enter an FTP address like ftp://[2001:db8::1234]/ for the
location, I get an error saying, 'Error resolving "[2001": Name or
service not known.'

Similarly, when I enter an SMB address with a username like
smb://example@[2001:db8::1234]/ I get an authentication prompt saying,
'Enter password for "[2001".'

Both of these suggest that the URLs are not being parsed correctly.

A workaround is to mount such resources using the "gio mount" command
and browse them in Thunar as normal. This suggests that the wrong URL
parsing is happening in Thunar and not GIO or GVFS.

I also get generic "connection failed" and similar errors with other
kinds of URLs, like smb: without a username, but I suspect the cause is
the same.

This appears to be caused by the fact Thunar performs some URL escaping
before attempting to load the URL:

/* try to parse the URI text */
escaped_text = g_uri_escape_string (text,
G_URI_RESERVED_CHARS_ALLOWED_IN_PATH, TRUE);
file_path = g_file_new_for_uri (escaped_text);
The second argument to g_uri_escape_string is a string of characters
that should not be escaped, but this does not include [ or ]. As a
result, the actual URL that Thunar attempts to load would be something
like ftp://%5B2001:db8::1234%5D/ which does not work.

One solution could be to include [ and ] in that second argument
although this may cause issues when these characters occur in other
parts of the URL (such as the path).

I pulled the latest version (4.17.8-1) from experimental and I believe
this bug/unexpected behavior is still present.

I have reported this issue upstream because I am fairly confident that
this is not distribution-specific.

This has been fixed upstream in version 4.18.8 and 4.19.0.
