#2623: GRASS won't start after creating addons

Having forced addons to install as per Ticket #2598 (still with
grass7.0.1svn-x86_64-unknown-linux-gnu-21_02_2015), GRASS fails to start,
due to what appears to be an issue when creating menu items for the
addons.

The terminal output is as follows:

Changing the name of the ~/.grass7/addons/modules.xml file allows GRASS to
start fine (but obviously with no addon menu items) and the addons appear
to start fine also (i.e. their gui's are created when calling up addons at
the terminal).

#2623: GRASS won't start after creating addons

* keywords: => menu, toolboxes, addon, loading

Comment:

I don't understand what is the environment? Do you have different non-
English locale? Which addons you have installed? What if you uninstall all
addons and install them again? How `~/.grass7/addons/modules.xml` looks
like? I don't know how to reproduce this error (it works fine for me in
both trunk and release branch).

My `~/.grass7/addons/modules.xml` looks like:

{{{
#!xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE task SYSTEM "grass-addons.dtd">
<addons version="7">
     <task name="r.geomorphon">

geometry using machine vision approach</description>

     </task>
     <task name="v.in.proj">

         </binary>
         <libgis revision="64733" />
     </task>
</addons>
}}}

Can you please attach your `~/.grass7/addons/modules.xml`?

Comment(by ewcgrass):

This is from Help-->about system:

{{{
GRASS version: 7.0.1svn
GRASS SVN Revision: 64713
Build Date: 2015-01-21
Build Platform: x86_64-unknown-linux-gnu

}}}

(please note that the build date shown above is incorrect and should read
2015-02-21)

I have by process of elimination determined that it is the section of the
$HOME/.grass7/addons/modules.xml file for "r.to.vect.lines" addon that is
causing grass to not start:

{{{
     <task name="r.to.vect.lines">
         <description>None</description>
         <keywords>None</keywords>
         <binary>
             <file>/home/rick/.grass7/addons/scripts/r.to.vect.lines</file>
<file>/home/rick/.grass7/addons/docs/man/man1/r.to.vect.lines.1</file>
<file>/home/rick/.grass7/addons/docs/html/r_to_vect_lines_example.png</file>
<file>/home/rick/.grass7/addons/docs/html/r.to.vect.lines.html</file>
         </binary>
         <libgis revision="64007" />
     </task>
}}}

Removing this section from the file now allows grass to start. However, I
see no menu items for any of the installed addons. Should there be menu
items for the addons? And if so, where in the gui would I find them?

I have attached the $HOME/.grass7/modules.xml file that now allows grass
to start.
