+                       <answer>
+                               <p>In recent Ubuntu versions (13.04, 13.10) the Taxomomic Editor crashes frequently (KDE) or freezes for some time (GNOME). The crashes in KDE are due to a bug which affects all Eclipse indigo (3.7) RCP based applications. Even this bug is currently discussed in the affected developer communities: <a href="https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1241101">launchpad bug 1241101</a>, <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=419729">eclipse bug 419729</a> the cause of this bug is still unclear.

+                               <p>In KDE the crash occurs when the oxygene_gtk is being used. Therefore switching to another GTK2 theme is known as a  temporary solution. The GTK2 theme Raleigh has been sucessfully used as a replacement to the oxygen_gtk2. You can either configure it globally or set the environmanet variable GTK2_RC_FILES for the application to run.</p>

+                               <code>GTK2_RC_FILES=/usr/share/themes/Raleigh/gtk-2.0/gtkrc "/path/to/EDIT Taxonomic Editor/TaxonomicEditor"</code>
+                       </p>
+                               <p>The font size is usually too big in the default configration of this theme. In order to have a nicer font, you can create a file named .gtkrc-eclipse in your user home folder with the following content:</p>
+<pre>style "eclipse" {
+        font_name = "Ubuntu 9"
+}
+class "GtkWidget" style "eclipse"
+</pre>
+                               <p>Finally, to launch the Editor, use following command line:</p>
+<p>
+                               <code>GTK2_RC_FILES=/usr/share/themes/Raleigh/gtk-2.0/gtkrc:~/.gtkrc-eclipse "/path/to/EDIT Taxonomic Editor/TaxonomicEditor"</code>
