There are several links to other Gnome documentations in the Evolution help that do not work, because they use # instead of / to refer to a subpage of the other help document. These are:

#: C/default-browser.page:29(section/p)
msgid ""
"Please see <link href=\"help:gnome-help#net-default-browser\">the GNOME "
"Desktop Help</link>."

#: C/default-browser.page:46(section/p)
msgid ""
"Please see <link href=\"help:gnome-help#net-default-email\">the GNOME "
"Desktop Help</link>."

#: C/mail-encryption-gpg-create-key.page:25(note/p)
msgid ""
"These steps are very technical. For average users we recommend using the "
"<link href=\"help:seahorse#index\"><app>Seahorse</app> application</link> "
"for managing GPG/OpenPGP keys."

#: C/mail-save-as-pdf.page:22(page/p)
msgid ""
"In order to save emails in the PDF file format, select <guiseq><gui>File</"
"gui><gui>Print</gui></guiseq> and then choose <gui>Print to File</gui>. See "
"<link href=\"help:gnome-help#printing\">the desktop help</link> for general "
"information on printing."

#: C/offline.page:28(page/p)
msgid ""
"If the problem persists and you are sure you have not clicked the icon, but "
"you can still reach the network from other apps on your system (browsers, "
"FTP, SSH, ping etc.) it may be that NetworkManager (NM) is not properly "
"configured. Many Linux distributions now use NM to manage their connections, "
"and if it is installed Evolution will use it to detect if the network is up. "
"However NM can be installed but not properly configured, leaving the network "
"working but not detectable by Evolution. (Note that other GNOME-based "
"applications may also fail for the same reason.) The solution is to "
"configure NM to manage your network interface. This is usually easy to do "
"but is outside the scope of this document. For more information please take "
"a look at the <link href=\"help:gnome-help#net\">Desktop help</link> or seek "
"help from your distribution support forums, mailing lists etc."

#: C/problems-getting-help.page:24(page/p)
msgid ""
"To receive help on problems you can send an email to the <link href=\"http://"
"mail.gnome.org/mailman/listinfo/evolution-list\">Evolution mailing list</"
"link> or talk to developers and other users in the IRC chat channel "
"#evolution on the server irc.gimp.net. To connect to an IRC server you can "
"for example <link href=\"help:empathy#irc-manage\">use the internet "
"messenger application <app>Empathy</app></link>."
