+I think there is a problem in my "dependency graph". As an example, 
+[here](http://poivron.org/~nil/misc/ikiwiki_buggy_index) is the index 
+ikiwiki generated for [my site](http://poivron.org/~nil/misc/ikiwiki_buggy_index)
+(note that the site changed since this index was generated).
+
+Some **HUGE** dependencies appear, like
+
+    depends=((((((....((((((A|B)|A)|C)|A)|D)|A)|E)|A)|F)|A)|G....)
+
+    depends=((((((....((((((A|B)|C)|D)|A)|B)|C)|D)|A)|B)|C)|A)|B....)
+
+Couldn't isolate the cause, but some sources for this problem may be:
+
+* related to the img module
+
+* very visible because one of my pages includes 80 resized images
+
+Other special things in my templates and site:
+
+* a sidebar with \[[include pages="notes/\*" template=foo]] while notes.mdwn has 
+  a \[[include pages="notes/*"]] and uses the sidebar; removed it, doesn't change
+
+* a template (biblio.tmpl) calling the "img" plugin with a template parameter as the
+  image filename; removed it, doesn't change
+
+* some strange games with tags whose page calls a "map" directive to show other tags
+  shile tags are also used in tagclouds (in the sidebar and in the main pages)
+
+* ...
+
+I observed these problems (same *kind*, I didn't check in details) on
+ 
+* ikiwiki 2.00gpa1 + v5.8.4 + Debian 3.1
+* ikiwiki 2.3 + v5.8.8 + Ubuntu 7.04
+
+I can think about stripping down my wiki source and making it available online for analysis.
