Lightroom 3.5 RC, Windows 7 x64 Ultimate. After upgrade, one photo in a folder in the main library keeps crashing LR35RC instantly. Usually after selecting the phone. Other photos in same folder are not behaving this way. Still testing.
Workaround: MOVE files in question (the JPG + RAW NEF) out of the folder; Sync folder to remove from catalog. Move files back to folder, re-sync folder to import. All settings of course are lost but now RC5 not crashing anymore.
Did not test restoring catalog to older version because I had too many edits between backups.
