[zim 0.28] TrayIcon crashes on click when more notebooks are open

[Peter-Alexander]

conditions:
 - zim 0.28
 - TrayIcon plugin active
 - two notebooks are open

action:
 - single left click on TrayIcon

effect:
 - closes everything (both notebooks and even the TrayIcon)

proposal:
 - hide all notebooks
 - keep TrayIcon showing up in tray

terminal output:

# This is zim 0.28
# Gtk2 version is 1.221
# compiled against gtk+ 2.18.2
# linked against gtk+ 2.18.3

It also crashes/closes when I close the two notebooks and then click on the TrayIcon.

Can not reproduce. Closing this report since the perl version of zim has been superseded by the python version (0.4x series).
