Comment 24 for bug 173861

Here is a reproducer for the crasher, not the rendering bug:

$ sudo apt-get install xfonts-bolkhov-75dpi gnome-terminal firefox
$ sudo dpkg-reconfigure fontconfig-config (and enable bitmapped fonts by default)
$ sudo fc-cache -fv
$ gconftool-2 --set /apps/gnome-terminal/profiles/Default/use_system_font --type bool false
$ gconftool-2 --set /apps/gnome-terminal/profiles/Default/font --type string "Courier 10"
$ gnome-terminal --window-with-profile=Default

Note, this courier is not from xfonts-75dpi but from xfonts-bolkhov-75dpi. Might have to coax gnome-terminal into crashing by trying to change the font.

Can get firefox to crash too by changing using:
Fonts for: Western
Sans-serif and serif fonts to 'Serene'
fixed width to 'Courier'
Default character encoding to be ISO-8859-1

For the rendering bug on a Gutsy desktop:
$ sudo apt-get install xfonts-bolkhov-75dpi
$ sudo dpkg-reconfigure fontconfig-config (and enable bitmapped fonts by default)
$ sudo fc-cache -fv

Now go to System/Preferences/Appearance/Fonts

Change the Window Title Font to Serene. Pre-patched libcairo2 will show the 'Preview text', patched libcairo2 will not.
