Lxpanel freeze after closing LibreOffice document.

As of Ubuntu 11.04, the package lxpanel 0.5.6 and Libreoffice 3.3.x, the bug still exist, freezing lxpanel after saving and closing current  ODF files. I suspected lxpanel bug, looking it over the Internet and haven’t found any confirmation that it actually does the freezing. While seeking answers over the Internet I’ve found this bug thread: (click here), which fixes my problem, I’m not 100% sure it will work on all cases though, but good enough to give it a try.

1. Install the necessary libraries and tools to compile the lxpanel 0.5.8 from  source.

sudo apt-get install libgtk2.0-dev libmenu-cache1-dev intltool

2.  Download the lxpanel 0.5.8 source from here, of check the newest version here.

3. Compile the source code. Go to the folder of lxpanel source and perform the following command:

./configure --prefix=/usr
make
sudo make install

4. Logout the current session or reboot your machine to confirm.

5. Done.
