SourceTree external diff crashes Git with libiconv-2.dll missing

Question

Various commands, including external diffing crashes the Git executable.  The commands don't run. The popup dialog is:

git.exe - System Error.  "The program can't start because libiconv-2.dll is missing from your computer. Try reinstalling the program to fix this problem."

I have tried configuring SourceTree to use the embedded and system Git with no differences.  System Git is Msysgit 1.9.5.

I had the same problems and I tried all the possibilities copying the dll all around.
SourceTree version 1.6.25. I never changed the embedded/system Git version option.
I think it happens because I unistalled old Git (version 1.8.3) with the curent one (I also have TortoiseGit correctly installed). Now my Git is 2.6.3.
At the end I solved the problem with this:
Tools >> Options >> Git >> Update embedded Git.
It pass from 1.9.5 to 2.6.1. and now it works.
