trunk doesn't compile with Qt 4.2.1

[Dov Feldstern]

Hi!

I'm getting the following error on linux, qt 4.2.1:
GuiApplication.cpp: In member function 'QAbstractItemModel* 
lyx::frontend::GuiApplication::languageModel()':
GuiApplication.cpp:479: error: 'class QSortFilterProxyModel' has no member named 
'setSortLocaleAware'


Thanks!
Dov

list this week.)
