[flow-tools] flow-export 0.56 segfaults

[Gerald Combs]

I recently installed flow-tools 0.56, and every time I run
"flow-export -f1" I get a segmentation fault.  Here's the gdb backtrace:

#0  0x0804a20f in format1 (ftio=0xbffff800, opt=0xbffff790)
    at flow-export.c:503

The variable "cur" is being referenced without being initialized.
