[Bug 52445] after upgrade the gtk library, when using someof fonts, display is missing.

[Strange]

Public bug reported:

Binary package hint: libgtk2.0-0

when upgrade from edgy to dapper, or only upgrade the gtk library to
 libgtk2.0-0 2.8.18-0ubuntu2. And using someof fonts such as wenquanyi or simsun, a pragraph of text splitted by space will only display the first word leaving the words after first space blank.
This bug could simply reproduced by using wenquanyi fonts and using nautilus to explore some directoies contains of word and spaces, such as "My Document". In this case, only the word "My" will be displayed.
I think it's a bug as everything is ok in edgy, and lots of people said, after upgrade, this bug is found.

** Affects: gtk+2.0 (Ubuntu)
     Importance: Untriaged
         Status: Unconfirmed
