ZDoom

It was the same issue as the one in MaxED's example.

No, I was trying to run this in Doom. Ok, that explains it. From the name of the item I assumed you extracted something from Blade of Agony.

???

I don't understand. Aren't you running this with Strife?
You're supposed to talk to a peasant, and the item in question should be to your right (on the green platform).

If you want to help, post at least something that WORKS!
This one has me talking to a hostile monster and the item is missing.

[s]Here's a testable example of Tormentor's issue.[/s]
Attachment removed.
[s]It will crash when trying to give the 'Eisenmann files' (when jumping to page 5).[/s]
quick edit: tested with ZDoom 2.8pre-1884-g7a96f91

fixed MaxED's crash. Since I have no idea what's up with the original thanks to Tormentor not giving any feedback, that gets closed.

Not sure if that's the same issue, but using nonexistent "nextpage" value does indeed crash ZDoom.

Apparently you do not want to get this fixed. Either post an example that can be made to crash reliably or I'll close this report.

I cannot do this without a working example!

It completes, but simply try to talk to the actor and try all the dialogue options, one will crash :)

I need something testable that actually crashes. When I test this it just completes without error, despite the missing brace.

Already found the problem: In the ZSDF script, scroll to the very bottom. I forgot to close page 4 with a bracket so page 5 was within page 4, that made GZDoom crash. Maybe you can add a error message in such a case.

Please post a small test map, not some cluttered fragments that first have to be assembled into something usable.

Here is a small summary of the setting that I have atm:

If I start all these together and do the final step (giving the scientist the AktenEisenmann), GZDoom crashes, bug report attached.
