File browser access crashes Blender

Description

System Information

Lenovo Thinkpad T440S
i5-4300U CPU
Embedded T4400 graphics
No GPU
8G RAM

Operating system:

Ubuntu 18.04.2 LTS
Codename: bionic
Kernel 4.15.0-64-generic

Graphics card:

None. Standard Intel T4400 chip set

Blender Version

v 2.81 alpha
2019-09-13 22:12
0547a7753643

Worked: (optional)

Could not duplicate the issue launching Blender via blender-softwaregl

Short description of error

Any file operation using file manager immediately crashes blender with following error:

blender: src/intel/genxml/gen75_pack.h:72: __gen_uint: Assertion `v <= max' failed.
Aborted (core dumped)

This includes opening, linking, appending .blend project files as well as attempting to save an image from the render screen.

Please note that file access NOT using the file manager seems to behave normally, ie File > Revert or File > Recover

Exact steps for others to reproduce the error

Start Blender and attempt to Open, Append, Link, Open Recent a project file. Or Help > System Info or save image from render screen. Blender immediately terminates before the user is prompted to select a folder or file so this is not project file specific.

I also tried deleting bookmarks.txt, recent-files.txt, startup.blend and userpref.blend. Allowed Blender to create a new config rather than updating a 2.80 version, same result.

My experience seems to be identical to what is described in T69461, however no AMD or GPU hardware is present in this system.

There have been a couple of fixes regarding the new File Browser since (your build is 10 days old...).

Could you check if this is still a problem with a fresh build from https://builder.blender.org/download/?

Actually this seems to be the same driver bug we had reported before. The description doesn't name the driver & version, I assume it's 19.0.8?
That would be important to know in this case. If so, you don't even need to test the newer build, that won't help either.

Julian,

It seems my OpenGL driver is 19.0.2.

Before attempting to update the driver, can you verify whether this issue affects systems using Intel processors with Intel integrated graphics (no AMD, no GPU)?

Thanks!

Also, my response to Philipp this morning bounced: 554 5.7.1 <noreply@developer.blender.org>: Relay access denied

So here's that reply ...

The following file operations crash Blender immediately:

File > Open
File > Link
File > Save
File > Save As
File > Save Copy
File > Import (I tried .FBX and .OBJ)
File > Export

All Image > file operations from the render screen.

However File > Recover and File > Revert work normally.

None of these crashes occur with the 2019-08-29 6b33bd1067dc build.

I see that this task is flagged "Needs information from user", please let me know what is needed if I'm holding things up.

Blender 3b23685c7dc1 build date 2019-10-01 19:51 still crashes when attempting to access the file browser on Ubuntu 18.04 LTS.

However I booted Ubuntu 19.04 from a flash drive and cannot duplicate the file browser problem running the same 3b23685c7dc1 build.

FYI - both Linux distros are using Mesa 19.0.2 , system-info.txt saved while running Ubuntu 19.04 is attached.

For anyone else with the Mesa drivers issue in Linux, here's the fix:

http://ubuntuhandbook.org/index.php/2019/10/install-mesa-19-2-1-ubuntu-18-04-via-ppa/

Should the above link disappear in the future, here's what it amounts to:

sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt-get dist-upgrade

To verify the version afterwards:

glxinfo | grep "OpenGL version"

To revert back to the original drivers:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:ubuntu-x-swat/updates

I've been running the Oct 28 build for a couple days in Xubuntu 18.04 LTS, no issues.

So far no developer was able to recreate this, which is a bit of an issue.
Don't know how to go about this TBH.

Julian,

Were they running the current LTS versions of any Ubuntu based distro? It was quite consistent for me with 18.04 LTS until I found the Mesa driver fix.
