RHEA-2004:488 - Product Enhancement Advisory

Topic

Updated gtk2, pango, and librsvg2 packages are now available.

Description

The gtk2 package contains the GIMP ToolKit (GTK+), a library for
creating graphical user interfaces for the X Window System. GTK+ is
used in the GNOME desktop and many other graphical applications.

The Pango package contains the text layout and rendering system used by
GTK+ and the GNOME desktop.

The librsvg2 package contains an SVG library based on libart.

The gtk2 and pango packages have architecture-dependent configuration
files that are located in /etc/gtk-2.0 and /etc/pango. This caused file
conflicts when installing 32-bit and 64-bit packages in parallel.

These updated packages move the configuration files into the
/etc/gtk-2.0/${host} and /etc/pango/${host} locations, thus allowing
separate configuration files for the 32-bit and 64-bit packages.
The binaries for updating these files have been renamed to add a
"-32" or"-64" suffix. The librsvg2 package, which depends on one of
the renamed binaries, has been updated to match this change.

These updated packages also fix a bug where GTK+ applications failed to
interpret certain key combinations correctly when used with certain X
servers. Problematic key combinations included such keys as the AltGr key.
For example, the problem occurred with Hummingbird, ReflectionX, and
X-Win32 X servers.

When the server was configured to use the Swiss German, the Swiss French,
or the France French keyboard layouts, it was impossible to enter any of
the Mode_Switched characters within GTK based applications. Traditional
applications such as XTerm and Emacs operated correctly. A simple test was
to enter AltGr+7, resulting in a pipe '|' output. When gnome-terminal is
run with XFree86, this succeeds, but with ReflectionX, it fails.

This problem has been traced to unwarranted assumptions in the GDK
keyboard mapping code about the data, which was being sent back from the
X server.

All users of gtk2, pango, and librsvg2 should upgrade to these updated
packages, which resolve these issues.
