[sqlmap-users] UNION injectable -> sqlmap stops to work

[-insane- <in...@gm...>]

Hey,

i've been using sqlmap and proxychains together for months and it 
allways worked fine for me.
Today i updated to the latest revision (3369) and i tried to find and 
use UNION injections.
In the past it was no problem, but with the latest revision i got one.
After sqlmap reports the following:
"target url appears to be UNION injectable with 22 columns"
it connects to the target one last time and afterwards it stops to work.
I tried some different targets and i also tried to use sqlmap without 
proxychains, but in all cases i got the same result.
Is it a bug or am i making a mistake?

The end of my output:

My very simple cmd:
proxychains sqlmap -u "http://www.xxx.com/index.php?id=1&type=0" --dbms 
mysql -p id --union-cols 21-22
