Worked: Anything else

Short description of error
Multiple Right clicking on blank space or Object results in SEGFAULT. test_scene.blend

Exact steps for others to reproduce the error

Start with basic scene
Modify Camera to Ortho, turn to x 60, y 0, z 45
Dublicate cubes into 4 cubes
Select one of them and create new material making it less diffuse than original
Apply new material to one more cube
Join 4 cubes into one object
Click multiple times on blank space or object
SEGFAULT
Based on a (as simple as possible) attached .blend file with minimum amount of steps

My thoughts
I think that DWM and Intel drivers may caused this problem.
Follow up
Under XFCE and LXDE SEGFAULT still present.

What is the Mesa version and driver you are using, i was not able to reproduce this on my similar Intel GPU on Ubuntu with Mesa 17.

Today I had a similar/related problem, that may have the same underlying cause. I had a memory access error during selection of one specific object. If another object was selected first, the bug didn't occur.

This also happens with Blender 2.78 on a i965 chipset, using Ubuntu 16.04. If you need more information, let me know.RoboCup_v22.crash.txt

I am new to the blender dev's, sorry if this post isn't in the right place.

Please don't change the status of a task yourself, confirmed status is for when blender developers are able to confirm the task by reproducing, i have not been able to do this yet on my Ubuntu system with Intel gpu.

You can try changing to a different Selection Method in User Preferences > System.

The segfault only occurs with OpenGL Select, OpenGL Occlusion Queries works fine.

I think this is a driver issue with OpenGL Select. So nothing we can fix (besides removing it which will happen in 2.8). I had this same issue on Intel HD 4600 on windows.

Is this similar to #48215, #50479 etc. ?

There were several reports concerning right click selection and Intel drivers on Linux.

https://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.77/UI#Other_Improvements_2

Since 2.77 the VBO are enabled by default and causes the Mesa Intel driver for certain chipsets to bail out.

Sounds correct I think we can close this see the reply in #48215:

In #48215#370821, @JulianEisel wrote:
Most likely this is caused by a bug in Mesa drivers for Intel which has been fixed in the meanwhile. Updating your Mesa package should fix the issue, or as a workaround you can change the selection method ({nav User Preferences > System > Selection Method}).
More precisely it was an issue with VBOs which are enabled by default since Blender 2.77, I also added a note to release logs recently to communicate this better (see https://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.77/UI#Other_Improvements_2).

Closing since it's unlikely an issue on Blender's side, we can reopen if the steps above didn't help.
