GRASS won't start after creating addons

[ewcgrass]

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).

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

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

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.

I cannot reproduce this error on my PC. Is it still valid?

Can you please try again with GRASS GIS 7.0.2 or later?

Is this still an issue with the new 7.0.3?
