Wireshark crashes when attempting any "File -> Export Packet Dissections -> *".

The crash appears to be happening in ui/gtk/range_update_dynamics() at line
1890 because g_cf being is NULL and it is dereferenced as follows:

    StringCchPrintf(static_val, STATIC_LABEL_CHARS, _T("%u"), g_cf->count);

I'm hoping that someone may be familiar with a recent change that was made that
might be causing this?  The crash does not occur with trunk-1.10.
