OK, that's a crash. Does it happen every time ? Can you try the older version of Gaim, available from the repositories described at http://gaim.garage.maemo.org/ ?

Note: If you wanna try the Gaim repository containing the older version, you must first remove your current version of Gaim, then the Gaim repository you currently have in your Application catalogue. Then, you must add the older repository and install Gaim again.
