When using the tags plugin, along with its option of "/taglist" instead of "/tag" (to produce clickable lists of entries instead of entries contents), the bottom next/prev navigation links are wrong.
Instead of "../plugin/taglist/<tag>/P<n>.html" it produces: "../plugin/<tag>/P<n>.html".
The link is obviously broken, so no page is displayed when clicking it.
I would have fixed it, but I have no idea where those navigation links are generated and how...
