Created attachment 107258 [details]
Page 1 shows a wrongly attached graphic, page 2 a right one

I have created a presentation in which I use lots of linked graphics. After saving and reopening some (but not all) graphics are not displayed any more. The lost graphics are marked with red text like this:

[FilePath]/graphicName.jpg%3FrequestedName=graphicName

This bug has already been reported (but not solved?) in a German LibreOffice forum: http://www.libreoffice-forum.de/viewtopic.php?f=7&t=13729

I have tried to unzip the odp-file, changedh the Content.xml by erasing all %3FrequestedName=graphicName, rezipped the file and it was working ... unfortunately only for a few days since the problem persisted. The same happens if I update the links via Bearbeiten/Verknüpfungen (I don't know exactly the English translation for that menu item: maybe Edit/Hyperlinks? ...): after saving they are lost again (but not all).

Does anyone have an idea why there is a string %3FrequestedName=graphicName getting added to the end of some xlink:href entries? Why is it happen randomly? I hope this bug is getting solved soon since it's very embarrassing to open a presentation with some linked graphics lost in front of an audience.

Best regards.
