Comment 6 for bug 1573307

I've downloaded the source package and debugged it... this seems related to a bug that is being discussed on the wget
mailing list at the following url: http://lists.gnu.org/archive/html/bug-wget/2016-02/msg00033.html

They say this happens with a small terminal window... but on me it happens no matter how big the terminal is...
i've tried to run wget with "quiet" mode and also chanding the progress from "bar" to "dot" and it works ...
anyways this is the backtrace done with gdb and you can see the padding is negative. Hope it helps :-)
