Menu merging with Ubnity top frame varies on User, sudo, or gksudo

[PaulANormanNZ]

Binary package hint: unity

Treid this now on three recent Unbuntu 11.04 releases, this one I am on at present is reporting as

1) lsb_release -rd
Description: Ubuntu 11.04
Release: 11.04

2) apt-cache policy texworks
texworks:
  Installed: 0.5~svn813~natty1
  Candidate: 0.5~svn813~natty1
  Version table:
 *** 0.5~svn813~natty1 0
        500 http://ppa.launchpad.net/texworks/ppa/ubuntu/ natty/main i386 Packages
        100 /var/lib/dpkg/status
     0.3~svn671-2build1 0
        500 http://nz.archive.ubuntu.com/ubuntu/ natty/universe i386 Packages

3) Starting texworks as a normal user nicely integrates the texworks menu in the Unity top frame as expected.

Starting as gksudo or sudo does not integrate the menu in the top frame but shows it as a normal application menu as under MS windows Xp say.

Have had a confirming report form a friend Stefan Löffler (the TeXworks ppa package maintainer himself https://launchpad.net/~texworks/+archive/ppa ) that this is indeed happening on his installs as well.

Not sure if this potentially creates a security issue or not, so have not ticked it in the form.

Its a bug in the way env variables are handled in gksu. It seems that gksu doesn't pass on the UBUNTU_MENUPROXY env variable on to the application, and hence the application doesn't display its menu in the panel.
