iPhoto library empty after upgrading to iPhoto 9.6

HI,

I have noticed this problem mentioned by others numerous times with no solution that has worked for me. Has a better fix been found other than recopying all of the files in the 'old masters' list into a new library, effectively losing previously created albums, etc.? Is anyone at Apple actually working this issue since it seems to be pretty widespread and apparently directly related to a bug in iPhoto 9.6?.

OK, first, i have no back up iPhoto library. I had one previously but my secondary external drive got full and I had to wipe it to rearrange a bunch of data. Had planned on re-backing it up when I opened iPhoto and uploaded some new photos from my phone, but this event happened and now I am out of luck...

My iPhoto library is stored on an external drive (Wester Digital my Passport for Mac) and has worked fine until yesterday when I plugged my iPhone 6+ in to upload photos and sync with iTunes. Upon booting up iPhoto, I got a notification that I needed to upgrade my library. I clicked on the upgrade function and was then notified that a mistake was found and a repair was necessary. The repair was ongoing when iPhoto froze and entire system failed, giving note that startup disk was nearly full. After doing system restart and opening iPhoto, I found all photos gone from iPhoto window. iPhoto is using the correct library and after looking at all internal files in iPhoto library, I found all photos had been moved to "old masters, old thumbnails, old previews".

Size of iPhoto library is still over 500 gigs, so data is there apparently. I immediately backed iPhoto library up, so at least this data has been salvaged, but I still can't access my photos. I have used iPhoto's rebuild functions sequentially all the way to full rebuild, with no photos being found. I then used iPhoto library manager app's rebuild function, and it also revealed no photos.

So, what can I do to sort this out? Needless to say, with 500+ gigs of photos, I am concerned. I am hesitant to do the manual rebuild using the 'old masters' option since I will lose all of my previously organized albums. Is waiting for Apple to issue a fix that will actually restore lost data only a dream or would that feasibly happen? Thanks in advance for any and all help that can be offered.
