>Description:
Editing a PR with a field of type multi-enum causes a segfault. The segfault is 
caused by a call to strpbrk() at line 752 of pr.c, in the subroutine 
verifyMultiEnum. The following output comes from gdb after submitting and edit 
with a multi-enum field:

Breakpoint 1, verifyMultiEnum (i=0x6bae0, value=0x6b019 "flour") at pr.c:731
(gdb) display curp
1: curp = 0x6b019 "flour"
(gdb) display separators
2: separators = 0x1f4 <Address 0x1f4 out of bounds>
(gdb) next
2: separators = 0x1f4 <Address 0x1f4 out of bounds>
1: curp = 0x6b019 "flour"
(gdb) next
2: separators = 0x0
1: curp = 0x6b019 "flour"
(gdb) next

Program received signal SIGSEGV, Segmentation fault.
0xff1d0820 in strpbrk () from /usr/lib/libc.so.1


So, something seems to be wrong with the 'separators' string.
