System Information
Windows 8 .. if you want to know more you'll need to tell me where the heck Blender saves the Help/System Info file. You don't document it and I can't find it.

Blender Version
Broken: 2.71

Blender crashes when editing a UV map.

Start Blender 2.71
Switch to UV Editing window layout
Switch to Edit mode
Select Shading U/Vs tab
Create a UV map. Any will do. Cube projection / Scale to Bounds works well for an example.
Select ONE UV face.
Enable SNAP for UV Element, select Snap to Vertex.
Press G to grab/translate the selected face.
Drag to snap to a vertex at another position. DO NOT FINALIZE the drag (ie, don't left-click)
Be a normal user .. forget you're dragging a part of the UV map and press "A" to select all.
Say "Well, damn, there goes a few hours of work!" when Blender disappears from your screen.

The "Help -> System Info" file should be in Blender! (Namely, in the Text Editor). Also be sure to always include a blendfile. Anyway, here's mine: #41201.blend

I'm getting:

Program received signal SIGSEGV, Segmentation fault.
0x0000000002954fbc in mul_v4_m4v4 (r=0x7fffffffdbf0, mat=0xc0, v=0x7fffffffdbf0) at /home/kevin/src/blender-git/blender/source/blender/blenlib/intern/math_matrix.c:522
522           r[0] = x * mat[0][0] + y * mat[1][0] + z * mat[2][0] + mat[3][0] * v[3];

And here's a backtrace: bt.txt

Blender says it created a file, so I looked for a file. The web page documentation does not even mention the menu selection, much less tell you it's not really a file (that's what you mean, right?) and you'll need to open something in Blender to find it. Since I only use Blender for modelling, I have no idea where or how to open a text file, nor how to find a non-file text file created internally. I did look, first, and would have included it if I could find it.

Why include the default scene? It seems to me that every copy of Blender comes with it.
