Use onedir to debug this issue.
Can you please confirm that the script called pyi_rth_qt4plugins is
included in the executable through ArchiveViewer? The script source code
is within PyInstaller itself (directory support\rthooks); it should be
executed before your own application starts.
Can you please put some debug prints in there and verify that it is
executed correctly? Does it add the correct directory to Qt's library path?
Are you using Riverbank's GPL installer?
Can you confirm that the DLL that PyInstaller ships are the one that you
are using in your development environement, and not DLLs from a
different version of Qt/PyQt that you might happen to have installed in
your system? A typical problem is that you have a Qt in your PATH that
overrides the Qt DLLS shipped together with PyQt.
