Mac OS X 10.7. Canon EDSDK Crashes with EXC_BREAKPOINT (SIGTRAP) in CFRelease

Hi,

I'm trying to use the Canon EDSDK with QT. That works quite smooth for all issues regarding the Camera Remote functions.
But when it comes to Raw development, I can't get rid of a crash EXC_BREAKPOINT (SIGTRAP) in CFRelease + 25.
The Canon SDK for Mac OS X seems to be written in Objective C.

The same code I'm using in QT 4.8.0 / x86 is working fine when compiling as 32bit in XCode 4, adapted to Objective C.

I tried creating a Cocoa Autoreleasepool manually, tried a lot of more things to track down the problem - without any success.
As soon as it reaches "EdsSaveImage" it crashes. :mad:
It gets a s far as printing out the width and height. Error codes are always 0 = EDS_ERR_OK

Any experience with Canon EDSDK or similar issues?

Code:

---

EdsError err=EDS_ERR_OK;
    EdsImageRef mimageRef;
 
    // Create FileStream
    EdsStreamRef inStream = 0;
    err = EdsCreateFileStream(
              path.toAscii(),
                kEdsFileCreateDisposition_OpenExisting,
                kEdsAccess_ReadWrite,
                &inStream
                );
    // Create ImageRef
    if(!err){
        err = EdsCreateImageRef( inStream, &mimageRef );
    }
    qDebug("LOAD %d",err);
 
    EdsUInt32 jpegQuality = 9;
    EdsTargetImageType imageType = kEdsTargetImageType_Jpeg;
 
    err = EDS_ERR_OK;
 
    // Create Target Stream
    EdsStreamRef targetStream;
    QString sPath = "testttr.jpg";
    err = EdsCreateFileStream((const char*) sPath.toAscii(), kEdsFileCreateDisposition_CreateAlways, kEdsAccess_ReadWrite, &targetStream);
    qDebug("CREATE %d",err);
 
    // Set SaveImageSetting
    EdsSaveImageSetting saveImageSetting = {0};
    saveImageSetting.JPEGQuality = jpegQuality;
 
    err = EdsGetImageInfo(mimageRef, m_imageSource, &imageInfo );
    qDebug("HEIGHT %d",imageInfo.height);
    qDebug("WIDTH %d",imageInfo.width);
 
    // Save Image
    if(!err) err = EdsSaveImage( mimageRef, imageType, saveImageSetting, targetStream);
    // Release
    if(targetStream) EdsRelease(targetStream);
 
    return err;
