( after refamiliarising myself with this code ) this behaviour is not at 
all expected.

It seems that base documents are doing something strange ( well maybe 
better to say different ) here, in fact if you add, save and then remove 
some image controls ( with embedded images ) then the Picture streams 
are never discarded.  With the other applications ( calc, writer etc. ) 
when you save you save you save to new storage and the storage content 
is regenerated from the document model so effectively the existing 
content is thrown away and recreated. In the case of basic of course 
some optimizations might occur like copying existing 'Basic' substorages 
to rather than writing  to the target storage based on the in-memory 
libraries model.

With that in mind and after doing a little testing I think your patch 
for loading the library in 
SfxDialogLibraryContainer::storeLibrariesToStorage is the simplest thing 
to do and should avoid any such problems in any other applications  like 
the one you mentioned ( that I cannot reproduce ) in calc. So I will 
push this ( and good job too tracking it down )

The issue with the leaking 'Picture/xxxxxxxxxx.png" etc. streams still 
remains, I guess I would need to understand what base actually does when 
saving with the existing content to see what we can do there, probably 
it is just a case of excluding the Pictures directory rather than 
blanket copying stuff.

thanks,
