Comment(by atagar):

 Uggg, this ticket fills me with rage. I've tried a couple different
 approaches to repro this problem in our integ tests but no luck. Things
 that I've figured out are...

 * The troublesome descriptor parses just fine when alone or with a handful
 of other descriptors in a tarball.

 * If validation is turned off then things parse correctly...

 {{{
 atagar@morrigan:~/Desktop/stem$ python example.py
 READING TAR
 279043 descriptors in tarball.
 READING DIRECTORY
 279043 descriptors in extracted directory.
 }}}

 * The problem is that this descriptor somehow causes thousands of
 descriptors to go unread in the tarball as you observed, yet I haven't a
 clue why that is...

 {{{
 atagar@morrigan:~/Desktop/stem$ python example.py
 READING TAR
 250048 descriptors in tarball.
 READING DIRECTORY
 279042 descriptors in extracted directory.
 }}}
