Thanks for the report. I understand some work is going on in implementing a new print dialog, which requires gtk 2.10. What version of gtk do you have installed?
I'm running Debian sid. I think, the libgtk2.0-0 and libgtk2.0-dev packages are waht you want to know.
Package: libgtk2.0-0 Priority: optional Section: libs Installed-Size: 4076 Maintainer: Sebastien Bacher <seb128@...153...> Architecture: i386 Source: gtk+2.0 Version: 2.8.20-5 [...]
and
Package: libgtk2.0-dev Priority: optional Section: libdevel Installed-Size: 8160 Maintainer: Sebastien Bacher <seb128@...153...> Architecture: i386 Source: gtk+2.0 Version: 2.8.20-5 [...]
So, it seems that I have only gtk 2.8.20. AFAIK There is no gtk 2.10 (and no gnome 2.16 :-() in Debian yet.
