Comment 3 for bug 503294

Perfect thanks, it would seem that we're using PyGTK calls that are only in 2.14 or newer, which is why that method is failing on RHEL 5.4.
I've committed a fix to trunk at revision 802, but this seems serious enough that I should probably do another release fairly soon. I'd like to get myself an old distro in a VM so I can test on python 2.4 and an old pygtk (mostly I'm using the latest Ubuntu releases, so I'm on python 2.6 and pygtk 2.16) to catch any others.
