Comment 4 for bug 414353

> Any possibility this could depend on which language is being used?\
No. I cange locale to en_us, bug still present.

I can`t speack C programming language, but it`s look like error in scroll box upper value calculation algorythm (launcher_iconview_set_category function from launcher-iconview.c file). I think, that author of first message said right.

If menu contains some like this (--- - group separator):
A B C D
E F G H
I J
---
K L M N
O P Q R
S T Y

row variable is 4, but must be 5. And I can`t found place with group separator height calculation.

Forgive me if I am wrong, but I newer wrote in C or similar language and smoke this sources only 5 minutes :)
