Bug#381679: libpango1.0-0: shape engine failure

[gulfstream]

Package: libpango1.0-0
Version: 1.12.3-1+b1
Severity: normal

When I use wxWidgets(GTK+ port) and hoops, which is a high-performance 2D/3D engineering graphics engine, the fonts (including menu and button, etc) in the UI missed, and get warning message in the terminal. The warning message is "Pango-WARNING **: shape engine failure, expect ugly output. the offending font is 'Sans 9.9990234375'".
