title: Not able to open MonoDevelop v 2.4.2
body: <p>When I try to open MonoDevelop this error appears in the console log</p>
  
  <pre><code>com.apple.launchd.peruser.501[249] ([0x0-0x13013].com.ximian.monodevelop[308]) Exited with exit code: 255
  </code></pre>
  
  <p>How can I fix the problem?</p>
  
  <p><strong>EDIT:</strong> Snow Leopard 10.6.8, MonoDevelop 2.4.2 and Mono 2.10.5.</p>
  
  <p><strong>UPDATE:</strong> This is the error if I try to run MonoDevelop from shell</p>
  
  <pre><code>LSOpenURLsWithRole() failed with error -10810 for the file /Applications/MonoDevelop.app.
  </code></pre>
  
  <p><strong>UPDATE 2:</strong> I've found the crash reporter for mono</p>
  
  <pre><code>FATAL ERROR [2011-09-03 15:06:25Z]: MonoDevelop failed to start. Some of the assemblies required to run MonoDevelop (for example gtk-sharp, gnome-sharp or gtkhtml-sharp) may not be properly installed in the GAC.
