In the updated gnome-core package (gnome-core-1.0.7-2) pushing the Help button followed by the Gnome Terminal Users Guide item fails with a message that the file /usr/share/gnome/help/gnome-terminal/C/index.html cannot be found. This file is not included on a rpm -ql listing of the (updated) package, although it does appear to be present in the original package from the CD-ROM. Paul Hughett
This bug still exists in gnome-core-1.0.39-3
This was fixed with the gnome-1.0.50 releases.
