<space> toggles side pane on ubuntu

This problem also existed with officially supported zim 0.43-2 in Ubuntu lucid.

Disabling <alt>-<space> in keyboard layout switching clear the problem. Enabling it back makes it happen again.

Commented out "group.connect_group( # <Alt><Space>..." (gui/__init__.py:line 1609) mapping assignment and it started to work.

Apparently gtk.gdk.MOD1_MASK does not work or gives false positive even when Alt is not actually pressed in the case when <alt>-<space> is configured for keyboard layout switching.

What component is used to define the keyboard switching shortcut? Might be helpful to also file a bug report for that component. Apparently it somehow sets up the gtk environment to always see an Alt.

Only thing we could do about this is to make an option to completely disable this key binding, but in an ideal world that should not be needed.

Waiting for further information - set to "incomplete".

I just installed Zim 0.49 on Archlinux on my laptop and my space key didn't work as expected (it toggled the tree view instead of inserting a space). Then I tried installing Zim on my workstation, also Archlinux, and the same thing occurred. After reading through the bug list I encountered this bug report, and indeed, I have the alt_space combination configured in Xorg to switch between keyboard layouts. The bug thus is still present in the latest version of Zim. I use Archlinux X86_64 with kernel 2.6.36 and X.Org X Server 1.9.2. A fix would be greatly appreciated as I use Greek and Hebrew keyboard layouts for my study besides the US layout.

Fix committed in rev377

Removed the Alt-Space keybinding to avoid any more of these issues. For users that still want it there is a hidden preference to enable it. The Ctrl-Space keybinding will be the preferred keybinding and can be enabled from the preferences dialog.

Released in zim 0.51
