+The tarball is at http://scratch.madduck.net/__tmp__recentchanges-segfault.tgz - unpack it in `/tmp` and `chdir()` to /tmp/cdt.taF18912, then run

+    # segfaults
+    git checkout HEAD^
+    ikiwiki --setup ikiwiki.setup
+    # segfaults
+    rm -rf wc/recentchanges
+    ikiwiki --setup ikiwiki.setup
+    # works
