Keynote crashing on Snow Leopard Is SFWordProcessing the culprit?

Question

After having smoothly updated to Snow Leopard, I get Keynote systematically crashing.
At first it was only with specific files, but now it will not even launch at all. Here is the crucial part of the error message within the file "Problem Report for Keynote":
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000
Crashed Thread: 0
Dyld Error Message:
Library not loaded: /Library/Application Support/iWork '09/Frameworks/SFWordProcessing.framework/Versions/A/SFWordProcessing
Referenced from: /Applications/iWork '09/Keynote.app/Contents/MacOS/Keynote
Reason: image not found
Is really this file SFWordProcessing the culprit? After reading similar posts about Pages, I tried to remove this file, but it has only worsened, even after reinstalling it.
It seems ironical that this Apple application is the only one that causes havoc on my new system. Any advice and suggestions for fixing this would be greatly appreciated.

Answer 1

Let me reply to my own question by simply providing the solution that worked for me. I still don't know the "culprit," but it may work for others as well.
I simply deleted the whole *iWork '09* folder in Applications, as well as the associated folder in the Library:
Macintosh HD > Library > Application Support > *iWork '09*
Then, I reinstalled the whole thing, and bing, it works!
Best wishes,
