    More details:
    The splash screen appears and gets to about 30 percent, then disappears.
    Before the patch, after the splash screen finishes its progress bar,
    the documents open, instead I get a core dump:
 
    wiz@yt:~> gdb /usr/pkg/libreoffice4-4.4.4.3/program/soffice.bin soffice.=
 bin.core
    [...]
    (gdb) bt
    #0  0x00007f7fe3c18eb9 in FcPatternObjectPosition () from /usr/pkg/lib/l=
 ibfontconfig.so.1
    #1  0x00007f7fe3c194aa in FcPatternObjectFindElt () from /usr/pkg/lib/li=
 bfontconfig.so.1
 
 Doesn't really look like a kernel or X bug to me -- looks like a
 vanilla bug in fontconfig, unless FcPatternObjectPosition is working
 on a graphics buffer or something.
 
 I don't suppose you can rebuild with debug symbols and try again, can
 you?
