Hello, 
I was reading the contribute wiki.
(Came here because automatic account creation is disabled) 
Below is an edit I suggest: 


Linkhttp://wiki.inkscape.org/wiki/index.php/Compiling_Inkscape_on_Windows_with_MSYS2

Section: Obtaining Inkscape Source.

Code: git clone <link> 

Edit suggested:

Common Error(possibly): due to slow internet connection.

error: RPC failed; curl 18 transfer closed with outstanding read data remaining 
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

Solution: 

>git clone <link> --depth 1
>git fetch --unshallow


Reference:

I think if solution to common errors is provided in contribute section it will encourage newcomers to contribute.

Please communicate whether this is worth adding in the wiki.

Regards and thanks,
Aditya.
