Problem with [[plugins/map]]:
# Observed behavior:
## given map:
\[[!map pages="blog/tags/*"]]
## received map:
<div class="map">
<ul>
<li><a href="../" class="mapparent">blog</a>
<ul>
<li><a href="../tags/" class="mapparent">tags</a>
<ul>
<li>life
</li>
</ul>
<ul>
<li>tech
</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
Note that you get "blog" and "tags", and they're both links, but "life" and "tech" are not links.
# desired output:
<div class="map">
<ul>
<li><a href="../tags/life/" class="mapitem">life</a>
</li>
<li><a href="../tags/tech/" class="mapitem">tech</a>
</li>
</ul>
</div>
Note that you you don't get "blog" or "tags", and "life" and "tech" are links now.

# Discussion
(Disclaimer: I don't know ikiwiki internals.)
Map tries to calculate a "common prefix" between the pagespec and the page being rendered, and then later does some substitutions using the prefix. But the path has /'s in it and the common prefix doesn't, so it never matches correctly. So, add the /'s.
