Crash in file access / project creation

Folks,

(Imagine tale of woe about finding a cross platform GUI IDE here).

I have monodevelop 0.6 running on mono 1.1.6-r1 with GTK# and Glade# (distro
is Gentoo, but I should point out I'm using very conservative compile flags).
It fires up fine except for a "socket already in use" warning and seems to be
OK until I try to create a new solution (I have tried a glade# one and a
vanilla console one). When I hit the "New" button after entering the project
info, monodevelop freezes. No errors or warnings. Here are the outputs of two
successive attempts:

I did the upgrade from 0.5 and 1.0.6 because the old verson crashed (with
considerably more debug information at the same point. In case it's useful,
here's a transcript of the earlier crash:

Sorry for the long post. Can anyone help?

Thanks,
