[scribus] Accented characters requiring 2 keystroke to be typed

[JLuc]

In scribus (1.5 svn version compiled on ubuntu) on ubuntu,
the canvas editing (wysiwyg editing) doesnt enable anymore
to type in some accented characters as
ê, î, ô, û, ï, ö, ü, Ê, À, Ô etc
These require 2 keystrokes : ^ + e, ¨ + i, ^ + E, ...

Other characters are typed in ok : é, è, à, À, É.
These only require one keystrike.

This happened with Qt5.2 and I have tried with Qt5.3 pre-RC version
and its not fixed yet.

The workaround is to type in a text editor and copy'n'paste from there... so its not a display issue.

In the "story edit" window, which is not wysiwyg, these characters get typed fine.

Do other people experience this same issue ?
