Code review comment for lp:~mzanetti/ubuntu-ui-toolkit/more-stable-ubuntulistview-tests

I get the error that this MR fixes (without applying the changes proposed here) in a branch when I run 'make check' with Qt 5.0.2:

After merging lp:~mzanetti/ubuntu-ui-toolkit/more-stable-ubuntulistview-tests I didn't get the failure anymore, so the MR seems to fix the bug for Qt50 also.
