Data corruption

[Sandor Bodo-Merle]

One more thing - tellico does not call the FileHandler::FileRef::~FileRef()
destructor, which means that several versions of the file are kept open -
and which makes the situation worse, as unix dont free the space till there
are open file descriptors. The below excerpt from lsof show several version
of the tellico file. You can see two truncated files during this session
with the sizes 9453568 and 4919296.

So when these files are closed btw (when is the FileRef destructor called)?
Only at tellico exit? Or eventually at the next save of the file, where
tellico reopens the file, and updates the FileRef object?
