Bug#274033: pango: selecting proportional font for GTK results in 'size 0' errors

[Kimiko Koopman]

Package: libpango1.0-0
Version: 1.6.0-1
Severity: normal
File: pango
Tags: experimental

When I choose a proportional font for GTK/Gnome (doesn't matter whether this
is done through the gnome-font-properties dialogs or through gconftool-2),
all gnome windows are resized to enormous horizontal sizes and menu and
such texts are rendered unreadably small (mere dots). This can partially
be circumvented (which is how I have been getting by for the past week or
so) by selecting a fixed-width font. Even so, all Gnome apps still spew
lots and lots of repeats of this Pango error to stderr:
** (galeon:1481): CRITICAL **: file pango-context.c: line 269 (pango_context_load_font): assertion `pango_font_description_get_size (desc) != 0' failed
(app name and process id vary of course, the rest is always the same)

I'm not sure if this is really a bug in Pango, or in some other part of
Gnome, since fonts are rendered normally in widgets not directly under
Gnome's control, such as Galeon's main window/view. It may or may not have
started after upgrading to Pango 1.6.0, but downgrading to 1.5.2 or 1.4.1
doesn't get rid of it.

If this is not a Pango bug, can you please tell me anyway what package
likely causes it, or how to get rid of it?
