This is buggy behaviour, that has been reported before.
Has your iPhoto Library already been upgraded to iPhoto 9.3 format? And is it without any corruption? I'd run the First Aid Tools on it, to be sure: Hold down the option and command-keys ⌘ while double clicking the Library to open it, then run "Repair Permissions", followed by "repair Database". If you then still cannot merge the library into your Aperture library, try this:
For me the following work-around help; maybe it will work for you too: Aperture requires not so much space, if the library to be imported is also an Aperture library, so convert your iPhoto Library to an Aperture library (this seems to be pointless, since both libraries are supposed to share a unified format, but still the type seems to matter).
- Open your iPhoto Library in Aperture by ctrl-clicking it and selecting "Open with Aperture"
- Then select all library items: folders, projects, albums in the Library Inspector and select "File > Export > Library" from the main menu bar.
- The exported Library will be an Aperture Library; try to import this library into your main Aperture library.
