Proposed patch to the bug
Accessing the cairo xlib backend via X11 forwarding on (big endian) HP-UX from
a little endian system leads to a segmentation fault.
The crash occurs in the _cairo_xlib_surface_add_glyph function. At line 1321 if
c is zero an infinite loop causes the segmentation fault.
The attached patch seems to prevent the crash.</pre>
