Description zeniko 2011-06-06 05:48:17 UTC 
Loading page 23 of Coranul.pdf from http://ge.tt/8wWt5q4/v leads to a null-pointer dereference due to fz_curvetov being called on an empty path.

testcase

BTW: It seems that Adobe Reader doesn't implicitly add fz_moveto(path, 0, 0) but instead just drops the path (the same for fz_lineto, etc.).
