System Information
Operating system: Linux, GNOME
Graphics card: Intel UHD 620

Blender Version
Broken: 2.93.0 to blender-3.2.0-alpha+master.95005bbe02cf (which just happens to be the nightly build I have; I assume it's still broken.)
Worked: 2.92

Caused by 3a907e7425

Short description of error

Opening some files from old Blender versions and then setting an Outliner window to "Blender File" causes segfaults.

Background:

At some point I recall seeing a comment from Ton doubting that anyone would still have useful files from Blender 2.2X or some other ancient version. Well, I found a source of hundreds of such files!

The FreedroidRPG project is still in semi-active development, but the main artist (who also worked on Elephants Dream, I believe) and all the other artists retired years ago. As a result, out of the 700+ .blend files in the freedroid-graphics repository, just 40 were authored using a Blender version newer than 2.49. The rest range between the 2.2X series (of which there are 271 alone) and 2.49.

Obviously, lots of highly varied minor issues are inevitable and normal when opening files that are very nearly as old as I am. However, this report is about a specific reproducible crash that seems to happen with a lot of the files I've checked, and a relatively recently introduced one as far as Blender versions go (broken since only June 2021).

…I believe the files that crash may have broken library links in common, or maybe armature animations… Not sure.

Exact steps for others to reproduce the error

Open one of the attached files in a recent Blender version.
If an Outliner area does not exist, change one of the areas into an Outliner.
Set the Outliner "Display Mode" to "Blender File".
Observe crash.

The crash can also be triggered by setting an Outliner to "Blender File" first, and then loading the file without loading its UI.

ingame_329.blend
all_123.blend
action_cook.blend

If the file headers are to be believed:
ingame_329.blend was authored using Blender 2.25.
all_123.blend was authored using Blender 2.30.
action_cook.blend was authored using Blender 2.49.

All three of these trigger the crash for me using Blender 3.1. all_123.blend was the one that I used to determine that 2.92 was the latest working version. No idea if this can also happen with files from more recent versions; There are only a handful of 2.5X files from that repo, and all of them are much simpler.

Lots of other old files can be found in the https://gitlab.com/freedroid/freedroid-graphics repository.

Caused by 3a907e7425

This is mainly due to unhandled IPO IDs I think.

Previously these were shown under UNKNOWN, now this asserts in some place (but still should not crash @JulianEisel?)
Will set High prio (since it is a regression -- even though a bit older... feel free to lower again if this does not seem appropriate)
