[libre-office-git-repo As seen, the request thread has OleEmbeddedObject::saveCompleted and OleEmbeddedObject::getVisualAreaSize on the stack; both acquire OleEmbeddedObject's mutex; but only getVisualAreaSize releases it for the call of OleComponent::GetExtent. The latter releases solar mutex, at which time, the main thread (locking the solar mutex) attempts to call OleEmbeddedObject::getCurrentState, which needs the object's mutex, which is still locked in the request thread. Avoid this, by passing the lock object to the implementation of getVisualAreaSize from saveCompleted.
