We need to know the following about your system:
* How you installed Awn (either compiled from source code or from a binary package from a third-party repository)
* The exact version of Awn - that is, if you have a development or bzr version of Awn installed, the bzr revision number
* Your Linux distribution (and version)
* Whether your system is 32 or 64 bit

Also, it would be very helpful if you could provide a backtrace of the crash - you can find out instructions with regards to how to do this at the wiki:
http://wiki.awn-project.org/index.php?title=SubmittingBugReports

i tried to follow the instructions from this site:http://www.howtoforge.com/mac4lin_make_linux_look_like_a_mac_p3
at the step where it asked me to install the Affinity from the terminal window i got the message that the package wasn't available. Anyway i saw that the Awn Manager was available at the System - Preferences menu, i Clicked on it but nothing seemed to happen. After i tried the terminal... you know the rest

how can i find the version number?

I have installed edubuntu 7.10 and also installed kubuntu. i choose from the logon screen which desktop to use. (Gnome or KDE)
My system is 32 bit

i paste all the commands and returns as the procedure on the wikki. Hope this helps.

It appears that you have two installations of Awn on your computer - one that I assume you compiled yourself that's installed in /usr/local, and the one from reacocard's repository that's installed in /usr. Please remove the one in /usr/local by doing the following:

* open a terminal and change the directory to the directory where you compiled Awn from source.
* run `sudo make uninstall`.
* check to see if awn-manager is still in /usr/local/bin by running `ls /usr/local/bin/awn-manager`. If it's still there, run `sudo rm /usr/local/bin/awn-manager` to get rid of it. (Awn before version 0.2.1 didn't uninstall awn-manager properly)

After you do that, please check to see if Awn still segfaults. If so, please get a backtrace like the one that you did earlier, and post it here on Launchpad.
