SHCameraCapture always E_OUTOFMEMORY

[Tony Otto]

I'm trying to use SHCameraCapture to grab still images. On a Symbol
(Motorola) MC35, I always get OutOfMemory when I call SHCameraCapture 
from my QMainWindow-based application.
The CECapture sample works. Even after it fails, I check
GlobalMemoryStatus() and it shows dwAvailPhys of more than 17MB. I
modified my parameters in SHCAMERACAPTURE to mimic the initial
conditions in CECamera (commented lines below). Any ideas of where I
can look?

Using:
    MS Visual Studio 2005 + SP1
    Qt/WinCE 4.4.0 siesta
    MS Mobile 6 Smartphone SDK

Code snippet:

       HRESULT hResult;
       SHCAMERACAPTURE shcc;
       ZeroMemory(&shcc, sizeof(shcc));
       shcc.cbSize = sizeof(shcc);
       shcc.hwndOwner = this->winId();
//      shcc.pszInitialDir = filePath.utf16();
//      shcc.pszDefaultFileName = fileName.utf16();
//      shcc.pszTitle = dlgTitle.utf16();
//      shcc.StillQuality = (CAMERACAPTURE_STILLQUALITY)config-
 >captureQuality;
       shcc.VideoTypes = CAMERACAPTURE_VIDEOTYPE_ALL;
//      shcc.nResolutionHeight = config->captureSize.height();
//      shcc.nResolutionWidth = config->captureSize.width();
//      shcc.nVideoTimeLimit = 1;
       shcc.Mode = CAMERACAPTURE_MODE_STILL;

       hResult = SHCameraCapture(&shcc);

       if (S_OK == hResult)
       {
