New bill crash in gnucash v2.0.5

[Graham Leggett]

Hi all,

I reported a crash in January where it was not possible to create a new 
bill with gnucash v2.0.4 on MacOSX Intel (latest version) - I have just 
tried to upgrade to v2.0.5, and the problem is still there.

This time round I have managed to get a proper backtrace out of it, 
which is included below.

I have also managed to create a screenshot of what the gnucash screen 
looks like when the crash happens.

To replicate the problem, try to create a new bill in a mostly empty 
datafile. After selecting a vendor, gnucash tries to render the new bill 
window, and at this point it crashes.

Any ideas?
