Division by zero when changing infill density

[gege2b]

Version

current dev (as of 3a3b24e )

Operating system type + version

Debian 8.6 x64

Behavior

It's an issue pretty similar to #3589 except one thing : I don't have to switch to 3D preview for Slic3r to hangs.

All I do is load the STL (witch have some errors but I don't think it's the problem here), let the background slicing to complete and simply change infill % from default 20 to 25% (or 30 or 15 or whatever). It hangs instantly.
weirdly, if I simply change the type of infill it doesn't hangs

So, right now, I just can't change the infill %

Anyway If I change the infill density with empty plater AND THEN load a model, it's all right.

(note : the four folowing lines may vary or simply vanish. The last is always here.)

STL : http://www.thingiverse.com/thing:1727943 (my daugher loves Skye ^_^ ) in this case. But I also tried with other error-free STLs with same results

####Note : Maybe this is the same issue than the one mentioned above, but it appears when doing something else, that's why I opened a new issue. Don't hesitate to close it if it was unnecessary

Make absolutely sure that your model is manifold. "Unable to close loop" errors are usually as sign that something else is wrong. The illegal division by zero, however, is definitely related to the bounding box issue. "Nothing unreal exists." - Kiri-kin-tha's First Law of Metaphysics.

Yeah, that's why I tested other STL witch are manifold (no error and already printed in the past)

OK, so except for the non manifold and the "loop" errors witch are unrelated, I still get the division by zero error.

I'll close this issue as it's a duplicate of #3589 (possibly fixed by #3591 I guess) , feel free to reopen it if needed for any reason

[gege2b]

Allright, problem gone since #3591 has been merged :)
