iPhoto Library no longer shows up in "choose file" dialog after migration

"I recently installed my dev copy of 10.6 and it automatically fixed the problem. Although I can't say for sure, some preference file must have not been properly updated after the migration. Reinstallation most likely updates those preference files correctly.

My best guess to fix this issue without reinstalling the OS would be to follow Bryan Schuetz suggestion of removing the iLifeMediaBrowser.plist file."

"iPhoto writes out its library's location to a file at ~/Library/Preferences/com.apple.iApps.plist, which other programs such as iMovie/iDVD/etc., plus that ""Photos"" section in the open/save panel use to figure out where the iPhoto library is. If that file is corrupt, that might be one reason the library isn't showing up. You can try removing that file, then opening and quitting iPhoto, which should cause it to write a brand new file to that same location.

Another possibility is that the file that iPhoto is writing out that other programs read to access the iPhoto library's content isn't being written out properly. Try downloading iPhoto Library Manager and see if it displays your library's album list properly. If it displays an error message instead, then take a look at the info on this page for common causes and potential solutions to such problms."
