[fixed] UV - vertex / tighten

[Hank]

Hi there,

Steps:

1. add any object
2. select face + uv mapping
3. do uv + unfold
4. for uv window select any vertex + tighten

[UV] vertex / tighten is causing crash_dump:

I think I already saw this kind of message for the wings_drag module before.

Thanks for report it. I'm going to take a look on it soon.

[EDIT]
Yes. It's already fixed in the next version.

p.s. Hank, I edited your post and removed the Long stack trace. The post got too long and usually it's not helpful - it's better to attach the dump file when necessary.
The most important was you provide a way to reproduce it.

Hi Micheus,

I've just started to work with 2.2.1 and the problem still exist:
(this time I tested with face -> tighten)

Ok. Let's take a look on that again. :/

Hank, there is no Tighten option for Face, but for Vertex mode.

I checked again in the official release and it's working for the way I tested.


Can you provide me any other information?

[Hank]

I think I have some solution to share my recordings - feel free to check it via Dropbox.

BTW recording was made on Linux.

[micheus]

Thanks. I already checked it and found it happens in a single case: only one face (or it's vertex) select.
I replied your PM.
