Crash when voting on a poll with a content warning

[NicoCharrua]

Describe the bug

If a poll has a content warning, voting sometimes crashes the app. I only noticed this while voting in a feed (and not after the post was opened), but that could be a coincidence.

To reproduce

1. Open content warning
2. Select an option
3. Vote
4. See crash

Do you have any more info as for how you can get this to happen? The issue itself shouldn't even be possible, but it somehow happens. If you could provide more info it'd be much appreciated

[NicoCharrua]

I have a timeline that looks like this

Opening a CW and voting makes it happen, after I click vote.

The crash doesn't happen all of the time, and polls with cws are pretty rare anyway, so the crash rarely happens.

Whether it crashes or not seems to be random, and I was never able to record it happening.

There's a similar bug (not crash) with voting in search results. If you search for has:poll, voting on a poll doesn't show the results.

I'm sorry I don't have any more info. If it happens again I'll get the crash log and a link to the post where it happened. Thank you

[LucasGGamerM]

It's alright. This is just a weird issue to happen

[NicoCharrua]

I just got the crash again, it was this post:

https://botsin.space/users/pollbot/statuses/112325455117950107

I clicked on a link to the post, opened the cw, voted, and it crashed. That means this doesn't only happen in feeds.

This is the post that took me to the poll, if that's relevant.

Happened again. This time I clicked into the post before revealing the content warning or posting, and it crashed.

I also got a screen recording this time. Video ends when app crashes.

The vote goes through, by the way.

Weirdly enough I just cannot reproduce this

Can confirm, CW isn't necessary though
