Тема: File corruption if stream contains vector properties

Hi
I’m opening an existing stream with existing Vector properties.
Then I try to remove and insert some properties.
As I commit (‘gsf_doc_meta_data_write_to_msole’) the file structure gets corrupted.
Is this a known issue?
 
Here is the relevant cpde:
for (const auto& key : keysToRemove) {
    gsf_doc_meta_data_remove(mDocumentSummaryInformation.get(), key.c_str());
  }
 
  for (const auto& property : propertiesToAdd) {
    const auto& name = property.second->GetGsfName();
    UniqueGvalue gvalue = property.second->GetGsfValue();
 
    gsf_doc_meta_data_insert(mDocumentSummaryInformation.get(), g_strdup(name.c_str()), gvalue.release());
  }
 
  const bool doc_not_component = type != OlePropertyStorageType::SUMMARY_INFO;
  const auto rc = gsf_doc_meta_data_write_to_msole(mDocumentSummaryInformation.get(), out, doc_not_component);
  MIPLOG(TRACE) << "Write metadata rc=" << rc;
 
Thank you
