1.0pre1: Freeze when saving settings the FIRST time balsa is run

[Paul Barnfather <plb clanger9 demon co uk>]

To reproduce:

rm ~/.gnome/balsa
start balsa
complete the druid
go to preferences and change something (I changed toolbar to icons only)
press OK - balsa freezes, pegging the CPU.

If I kill and restart balsa, I can save preferences just fine, this
ONLY happens the first tile balsa is run.

I don't know how to debug problems like this, but pressing ^C in gdb
leaves me with this backtrace:
