Description Dawid Lorenz 2007-06-03 11:41:17 EDT

When Application Font size is set to 7 (via ), Nautilus crashes. Chosen font is
DejaVu Sans Book, but crashes with any other.

Comment 2 Zoltán Magyar 2007-07-12 07:14:51 EDT

I could reproduce the bug using: Gnome 2.18.2, Nautilus 2.18.1-2.fc7 and Pango
1.16.4-1.fc7
I think the same bug is reported at gnome:
http://bugzilla.gnome.org/show_bug.cgi?id=454884

Comment 4 Alex Kloss 2007-07-17 20:00:24 EDT

Confirmed on Gnome 2.18.3, Nautilus 2.18.3-1.fc7

The error is being generated from eel's
eel_pango_font_description_get_largest_fitting_font_size function. The function
is passed a minimum font size and a maximum, but it will return an error if the
maximum is smaller than the minimum. Since the minimum font size appears to be
8, a size of 7 will cause the function to return an error. Then, when Nautilus
calls Pango to set the font size, it crashes, because Nautilus is passing Pango
an error value as the arguments.

The call to the function can be found at line 371 of
src/nautilus-sidebar-title.c, from Nautilus SVN.

Fixed in 2.20.0-3.fc8
