segfault in new ledger code

[Jack Ostroff]

Thomas,

Per your suggestion in the Wayland thread, I just recompiled with  
UNFINISHEDFEATURES enabled.  Selecting the new ledger gives me an  
immediate segfault, from both 5.0 and master, and whether or not I have  
already selected an account.  I'm pretty sure I can easily enough get a  
backtrace, but before I do, what other information would you want to  
help debug?
