+Font cache issue
+----------------
 
+The font cache doesn't record whether it was build with
+pdf.use14corefonts enabled or not, and the font name "Helvetica"
+happens to match "Helvetica Narrow", whose metrics are included with
+matplotlib, and using that AFM file without including the font itself
+breaks the output.
+
+As a workaround, please reset the font cache by deleting
+~/.matplotlib/fontList.cache each time you enable or disable
+use14corefonts.
