Well, one likely culprit is the font cache. This is corroborated by  
the file's being "fixed" after restart and working on linux. I don't  
know if acrobat uses the same files as preview and TS.

There are some free programs that clear out caches, such as Onyx and  
fontnuke.

But maybe someone sees a problem with the code below---although it's  
not clear why it would create a good pdf on one run then not on the  
next, if the code is the same each time.
