Bug#250720: dependencies broken (wrong pango modules in libpango1.0-0?)

[Stephan Rudlof]

Package: libpango1.0-common
Version: 1.4.0-3

The pango-querymodules script looks at the wrong place after installing,
but probably this is just the tip of the iceberg...
Consequences: this breaks starting of mozilla1.6 (luckily I have 1.6a
locally installed, too)...
