Exploding edge-group, strange result.

[jolran]

Hi!
Just wondering why this is happening.
I made a group with entities that where red 2d-face polygons. Inside that group another group with only edges.

The plan was to explode the edgegroup to "break" the edges, which they did. BUT some faces came out with no material in spite they where not, what you may call it "broken" by any edge, wierd!

I can reproduce this problem. Stoping the code before the explosion, and doing the same explosion manually in SU. Or do the same thing modeling in SU.

Here is a pic with the edges reselected after the explosion.
I could always do an intersection instead no big deal, but thought exploding edges would work fine as well...
Bug? Or normal behavior I did not know about.
