Hi Martin,

AFAIK from reading your old post with a fuller backtrace:

The throw is done in sfx2/source/view/frmload.cxx in detect and the catch 
should come in:

framework/source/dispatch/basedispatcher.cxx in the routine:

 BaseDispatcher::implts_detectType( const css::util::URL&                                  
aURL        , css::uno::Sequence< css::beans::PropertyValue >& lDescriptor 
, sal_Bool   bDeep       )


Here are the try and catch pieces:

        try
        {
            sTypeName = xDetection->queryTypeByDescriptor( lDescriptor, 
bDeep );

(parts cut out here)

        }
        catch( css::lang::WrappedTargetRuntimeException& exPacked )
        {
            // Handle occured exceptions during type detection.
            css::ucb::CommandAbortedException exAbort;
            if( exPacked.TargetException >>= exAbort )
            {
                sTypeName = ::rtl::OUString();
            }
            else
            {
                throw;
            }
        }

So it would be interesting to change this catch to catch everything just to 
make sure the stack walkback to find the catch is close to working and 
then check the type of the exception.

I would simply add debug print statements to these two methods to confirm 
if the catch is made but somehow it is not an exAbort and so another throw 
is done.  If you do not get the right catch, try changeing it to catch 
everything "..." and the print out the type of whatever is caught.

Please let me know what you see.

Kevin
