I'm working with a Custom member based on sampleremember
(http://svn.plone.org/svn/collective/Products.remember/trunk/Products/remember/examples/sampleremember/
)

It was created basically using search and replace based on sampleremember
When I try to install it via the portal_setup > import

I get the following traceback

.../plone/portal_setup/manage_importAllSteps
Traceback (innermost last):

http://svn.plone.org/svn/collective/Products.remember/trunk/Products/remember/examples/sampleremember/profiles/default/membrane_tool.xml

I found an interesting work around:
changing my profile's membrane_tool.xml from this:

 <?xml version="1.0"?>
 <object name="membrane_tool" meta_type="MembraneTool">
  <membrane-type name="SampleRemember">
    <active-workflow-state name="public" />
    <active-workflow-state name="private" />
  </membrane-type>
 </object>

To this:

<?xml version="1.0"?>
<object name="membrane_tool" meta_type="MembraneTool">
  <membrane-type name="SampleRemember">
<!--    <active-workflow-state name="public" />
    <active-workflow-state name="private" />
-->
</membrane-type>
</object>

got rid of the error.
Based on the traceback, and my investigation, there seems to be an
issue with membrane's category mapper, I haven't dug deep enough to be
sure, but I figure someone more familiar might know what's going in.

For the moment, I'll map active member states manually TTW.
