crash, rev 12369

[Mark Johnson]

I'm using rev. 12369.  Apologies if this has been fixed; I'm still 
compiling the latest rev.

To reproduce:
1. open gnucash
2. Choose Tools->Commodity Editor
3. Click Add
4. Full Name: CPR
    Symbol/Abbreviation: CP
    Type: TSX
    Fraction traded: 1/1000000
5. Click OK

Here is the output from gdb:
Program received signal SIGSEGV, Segmentation fault.
