PyQt and i18n, only "half of it" is translated

[NebuK]

Hi,

i wrote a project in pyqt and wanted to let it do i18n now. so i wrapped all my texts in self.tr() and wrote a .pro file like this:

SOURCES = main.py models.py
FORMS = ui/beans.ui ui/blends.ui ui/edit.ui ui/mainWindow.ui ui/profile.ui ui/roast.ui ui/select.ui ui/settings.ui ui/temptime.ui
TRANSLATIONS = roasterbase_de.ts

SOURCES = main.py models.py
FORMS = ui/beans.ui ui/blends.ui ui/edit.ui ui/mainWindow.ui ui/profile.ui ui/roast.ui ui/select.ui ui/settings.ui ui/temptime.ui
TRANSLATIONS = roasterbase_de.ts

To copy to clipboard, switch view to plain text mode 

then i did a pylupdate4 on that pro-file and translated everything in linguist. ran lrelease on the pro file and it says that ~140 finished entries are there. now i installed a translator onto my QApplication:

app = QtGui.QApplication(sys.argv)
 
    translator = QTranslator()
    print translator.load("roasterbase_de.qm", ".")
 
    app.installTranslator(translator)

app = QtGui.QApplication(sys.argv)
    
    translator = QTranslator()
    print translator.load("roasterbase_de.qm", ".")
    
    app.installTranslator(translator)

To copy to clipboard, switch view to plain text mode 

load() returns true. Thing is, only half of the stuff is translated, only a few dialogs but not all and some table headings - but again not all...

where could i start looking for the error?

Thanks in advance

PS: the project is available on svn://ghostdub.de/roasterbase
