Bug 160792

Description of problem:
On a certain PDF document evince freezes up when I try to enter a page number.

This is fairly easily reproducible.  I'll attach a reference to the document
which is available internally.

Version-Release number of selected component (if applicable):
evince-0.3.1-1
poppler-0.3.2-1

If I run under gdb, the backtrace looks like:

from stracing it, the application is stuck doing:
