[New issue] Importing .NET types causes ImportExceptions (zipimport handler)</span> <a href="http://ironpython.codeplex.com/workitem/34602">view online</a></div><p>User sopelt has proposed the issue:</p><p>"When hosting IronPython in a C#/.NET application the first import of a .NET type (and possibly non-zip python modules?) causes an internally thrown and ignored <code>IronPython.Runtime.Exceptions.ImportException</code> having <code>not a Zip file</code> as its message.<br />
<br />
This seem to happen during initial construction of the <code>zipimporter</code>.<br />
<br />
In situations where third-party libraries are being debugged or profiled in a project using IronPython this can cause lots of unwanted exceptions and complicate development.<br />
<br />
A minimal example could look like:<br />
<pre><code>namespace ConsoleApplication
{
using IronPython.Hosting;
class Program
{
static void Main(string[] args)
{
var e = Python.CreateEngine();
var source = e.CreateScriptSourceFromString(@"from System import Guid");
var result = source.Execute();
}
}
}</code></pre>
with the resulting stack at the time of the unwanted exception as<br />
