problems with roxterm 2.X

I've just tried to switch to a newer version of roxterm - without luck.

I have two problems with roxterm (2.4.2 from
https://launchpad.net/~h-realh/+archive/ppa, oneiric ) and 2.0.1 from
source code:
- roxterm-config segfaults when I try to edit a profile ("properties")
(2.4.2 only)
- roxterm segfaults if "scrollbar_pos" is set to zero

Both work fine with 1.13.5
