Works for me (47.01). You'll need to provide a save which crashes to work out what's going on here.

Upload to Bay12's file server and post a link here:

talk -> begin a performance -> tell a story -> choose '... person or creature' -> segfault

generated in 0.47.01, crashes in .01 or .02

only modding is to change tiles for grasses and shrubs

default linux package downloaded from bay12 manually installed on Arch linux

I may have some time tomorrow to try generating a new world.

So it's definitely not 100% of the time, nor 0%

OK, so...

I exported the w.g. parameters from the save I linked above.

I then regenerated the world in 0.47.02 and the crash doesn't happen.

But, I also regenerated it in 0.47.01 and the crash also doesn't happen. I made sure to start at the same place and as part of the same religion.

In the linked save, I had been playing for a while before I found the crash. I had gone new places, met new histfigs, and learned new things. It seems likely to me that when first starting out, the adventurer doesn't know about the "person or creature" that triggers the crash.

So, just because it doesn't crash at the beginning, doesn't mean it won't crash sometime later.

I believe the storytelling crash occurs when Villains having fake identities show up on the story telling name-list.

I can replicate this crash by starting in a human civilization with nearby tower, traveling to the big city, head to the fortress, and ask around using Persuasion about the local corruption. As soon as the local Vampire or Intelligent undead villain is referenced, (or not mentioned with blank placeholder), this is when storytelling becomes catastrophic. Funny thing, if you manage to find and kill them, the crash goes away.

Pretty simple to test then. Just start up a party, have one member take on a secret identity, then have another tell a story about him. Does that result in a crash?

No it does not. So far I encounter the problem in a world generated in unmodded in 47.04 and another in 47.05 (running Ubuntu Linux). I start an adventurer (no party) in a human civilization, visit the human sites using the story-telling feature and the intrigue/persuasion like an in-game 'Legends' to learn the lore. Once I come into contact with, or hear mentioned, a certain Vampire or intelligent Undead, the game will always crash when I select tell a story about a person. It does not story-tell crash if I start a new character, but it does once that character encounters the villain. My fix has been to copy the game and load legends into another workspace, currently trying to track another down and kill it to confirm that this gets rid of the issue.
