python3-qt5 Strange behaviour.

[VinsS]

With the script attached on Precise, the window appears in the top left of the screen and its size is approximately 20 x 20 pixels. At launching all the screen is disturbed and sometime I have a crash report for the application Marco (Nautilus in Mate).

On Trusty, the window is appears at the right size but without his menu bar. I've made some tests with other scripts and the menu bar is always hidden.

This looks similar to bug 1170384, which is fixed since Saucy.

This is probably bug 1362104, which is fixed in Utopic. As a workaround, remove appmenu-qt5 package.
