Please don't close this bug as a duplicate of an unrelated report just because it's a spawner crash bug. Not all spawner crashes are caused by invalid EntityIDs - this one has a unique cause unrelated to that.
If a spawner has an EntityID of "Painting", regardless of the provided SpawnData/SpawnPotentials, it will crash the game. This is due to an NBT loading issue, where the game recognizes "Painting" as a valid ID, but attempts to create one with a null world (spawners do this for the entity spinning in the spawner cage).
Unlike the majority of entities, paintings will crash when loading their NBT if their world is null, and there is no workaround to this (not even having an entity ride the painting will fix it).
Steps to Reproduce:
Import the attached schematic into your world.
Observe that you immediately crash when approaching the chunk containing it.

Kumasasa: I was able to reproduce with a vanilla SSP world with updated Java. I want to say it's duplicate of something, but I forget which ticket.

This is strongly related to MC-9788, but that was fixed for 13w09a, maybe only a partial fix.
The immediate cause of the two crashes differ; MC-9788 seems to be a NullPointerException in the EntityItem class, while this is a NullPointerException in the EntityPainting class.
From what I can tell in Minecraft Coder Pack, this is the cause:
public void writeEntityToNBT(NBTTagCompound par1NBTTagCompound)
{
par1NBTTagCompound.setString("Motive", this.art.title);
super.writeEntityToNBT(par1NBTTagCompound);
}
Spawners call this method when attempting to load NBT data into a painting. Essentially, the spawner creates a dummy tag, tries loading the existing data into it with the above method, and then merges the contents of SpawnData (if any exists) into the dummy tag. The problem is, that method makes the assumption that the painting's Motive (the art it displays) has already been defined. The crash happens before SpawnData even has a chance to define it.
From what I can tell, the reason this bug also existed for items is pretty similar: the Item entity's writeEntityToNBT method would assume its item has been defined, before SpawnData was even given a chance to define it. The fix was to only write the item if it already exists (i.e. "if (this.getEntityItem() != null)", in MCP).
Also, apparently for some reason my computer was stuck using an older version of Java. I uninstalled; hopefully it'll use the right one now.
Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

This ticket is incomplete without the requested information, no response has been received within a reasonable time and we are assuming the issue has been resolved. If you are still experiencing this issue, we can reopen it at your request.
Please review the guidelines before reporting issues.
Excuse me, but what was the requested information? Mod Talven requested me to update the Affected Versions for 1.7.2 on 27/Nov/13 2:55 PM, and I did so by 30/Nov/13 6:40 PM. That time frame seems reasonable to me; should I have also posted a comment confirming that I've updated the tag?
I wasn't asked for 1.7.4, but rather 1.7.2. Sorry, but I haven't had the time to check all my tickets for 1.7.4. At any rate, I've updated it for that.

Still in 14w02c, but with a different crash.
Can confirm in 14w08a with /setblock ~ ~ ~ mob_spawner 0 replace {EntityId:Painting}
Still a concern in 14w10x
On 1.8.1

Related to MC-66298.

Confirmed for ItemFrames and Paintings
1.8.5
1.8.6
15w34d

Cannot confirm for Items
Like the reporter said it might be caused because the game can't render it. This makes sense as changing the TileX
, TileY
or TileZ
value causes Minecart to teleport the ItemFrame/Painting to this position.
One thing interesting to note is that trying to set TileX
, TileY
or TileZ
manually results in a crash of the (internal) server.
Client crash report (no TileX, TileY and TileZ)
