System Information
Operating system and graphics card
Linux Mint 17.3
Dell Inspiron 15R with Intel Graphics

Blender Version
Broken: 2.79.1 (via Thomas Sheix PPA)
Worked: Previous edge version (2.78.x series via Thomas Sheix PPA)

Clicking on default cube (standard default start) causes blender to crash to desktop. Also prefs from previous version didn't seem to carry over, despite using the option to do so. (Usually with most PPA updates it was seamless.)

Edit:
Seems to work when loading another file from the start. Still some more testing, as I was not expecting this. Going to try deleting the default scene. (Corrupted perhaps?)

Deleted it, and restarted with it. Still crashing on cube selection. Something wrong with default scene being generated?

Edit 2:
Default scene being generated seems broken for some reason. Copied over the default scene from the .config files for the previous version and now it doesn't crash when selecting the cube. Going to try generating some new meshes, to see if they are broken. (Could be some attribute or data?)

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

try running blender via command line blender -d > debug.txt and see what happened. After blender crash you might want to press Enter several time.

You should also use blender from https://www.blender.org/download/ and test with that. Console output would help also.

Seems that the default scene was broken. Messed around a bit, and replaced it with the default scene from 2.78. No crash.

The auto-generated default scene (deleting previous) also causes a crash when selecting the cube. Something is odd there. I'll let you guys know if anything else comes up.

I repeat: Try blender from blender.org, not repo. And also that console output might help.

Hope that helps...
For the meantime, I think I'll just manually copy over the previous version's default scene again as I haven't been able to easily trigger a crash yet .

I'd still would like to know if this happens on official build, taken from blender.org/download, not from some repository.

Seems to happen with the (still official?) version 2.78c. Oddly enough it didn't happen with the previous repository version of the 2.78 series. (I think that's where the old defaults were being pulled from.) Then it seems to be fixed in the 2.79-rc2-linux-glibc-x86-64 version, but is a problem with the 2.79.x PPA.

To be honest though, I had a pretty good run through the 2.78.x with the buildbot PPA. (Was about as good as stable for the most part, but with newer rendering features which were great.) But I'm not sure what goes on between the official compressed folder releases and the package maintainers, as I'm mainly a user and liked the convenience of updates/bugfixes. But one would think there would be some consistency between the two, other than one variant being updated quicker or more incrementally. Seems like some stuff got forgotten or left out on some major version change. (And on the contrary, there was a missing lib2to3.py in the official release on Linux which was there in the PPA. That caused problems with a couple add-ons. However I suppose that's it's own topic, but hopefully something that's been resolved.)

Almost certainly the previous settings have a different Selection Method under User Preferences > System, there's some known issues with Intel driver bugs that give backtraces as reported here. Changing to Occlusion Queries should solve the problem.

For Blender 2.8 we'll change the selection code completely to avoid the problem, for now we consider this a known issue.
