Comment 0 for bug 1264719

I just build a GTK3 Inkscape on OS X 10.9 using MacPorts. The app seems to work, but I get a lot of these messages on the console when using the calligraphic tool:

*** BUG ***
In void pixman_region32_init_rect(region_type_t *, int, int, unsigned int, unsigned int): Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

lldb gives me this while breaking on the suggested symbol:
