PDF crashes pdffonts

I created this PDF to test some font issues.  When I run pdffonts on this file,
it crashes with a segmentation fault.

Program received signal SIGSEGV, Segmentation fault.
__pthread_mutex_lock (mutex=0x28) at pthread_mutex_lock.c:50
50    pthread_mutex_lock.c: No such file or directory.

backtrace:
