--- Comment #13 from Julien Nabet <serval2412 at yahoo.fr> ---
Caolán: I tried to understand the crash with the bt but for a reason I ignore,
m_sCompatibleObjectDescription is unreadable whereas m_aDescriptor is ok:

here's the output of p this:
{<TransferDataContainer> = {<TransferableHelper> =
{<cppu::WeakImplHelper<com::sun::star::datatransfer::XTransferable2,
com::sun::star::datatransfer::clipboard::XClipboardOwner,

      mxTerminateListener = empty uno::Reference, maFormats =
std::__debug::vector of length 0, capacity 1, mxObjDesc =
std::unique_ptr<TransferableObjectDescriptor> = {get() = 0x0}}, 
    pImpl = std::unique_ptr<TransferDataContainer_Impl> = {get() = 0x47e3950}},
m_aDescriptor = {m_pImpl = std::unique_ptr<svx::ODADescriptorImpl> = {get() =
0x47e39d0}}, 
  m_sCompatibleObjectDescription = <error reading variable: Cannot access
memory at address 0x99999999999999e8>}

I tried to trace where ctr with some fprintf(sterr, but nothing.
