Hi. a small bump. I also get CTD when near Karthspire but i found on god knows what forum that Delphine might be the cause for the crashes. So using the console i selected her and disabled her, coc to KarthspireCamp aaaaand not CTD. ........... Tested with the classic method of getting to places in Skyrim : fast travel to Markarth and walk there.... boom CTD. dang. ........... Tried with both Delphine and Esbern disabled, only me and Lydia: - fast travel and walk to the damn place .... CTD - coc to the location .... no CTD So me and Lydia killed all the enemies and the dragon, entered the cave, killed some more stuff, past the puzzles, got at the temple door and went in. Inside i enabled them, waited one hour then they went and did what they supposed to do. So this method seems to work ( for me at least ) but i got to get the loot and the dragon soul that is outside the temple and finished the quest. Hope this helps someone and sorry for my bad English.
