For the record:
This bug is still present in Keynote 5.0.3 (791). I have also saved a keynote presentation, only to find out that it had become corrupted. After reading this forum, I unzipped the keynote presentation and found out that it is indeed the index.apxl.gz that is missing. The thumbnails are unfortunately to small to be able to read the text, so I'm left with recreating the entire presentation.
I did notice a strange behaviour in Keynote/MathType when I last worked on the presentation. After having inserted about 5 equations with MathType, all subsequent equations weren't properly sent to Keynote when I closed MathType. Instead, they were placed into Keynote as empty, transparent grey blocks of one character wide (as if it was a selected empty white box).
I checked the checkbox 'Save new documents as packages', so I can at least check if the presentation is still there when I quit keynote. Which makes me wonder, would it be possible to configure Keynote to run an Applescript when a presentation is closed? The script would check the saved presentation and see if the most important files are there and prevent the presentation from closing if, for example, index.apxl is missing.
