Description jutaky 2013-07-10 13:58:20 UTC 
Segfault in go_image_get_pixbuf when exporting to xls.

Git versions of glib, goffice, gnumeric, libgsf and libxml2.

Test case: http://jutaky.com/fuzzing/gnumeric_case_8407_4552_2xls.gnumeric

Segfault triggered by opening the test case with gnumeric and using Save As and saving as xls.

Alternatively running "ssconvert gnumeric_case_8407_4552_2xls.gnumeric out.xls".

Backtrace from ssconvert:

Program received signal SIGSEGV, Segmentation fault.
