Nice catch, Rico. That bug resulted in a fix which was released in libgxim-0.3.2-4.fc10.i386.rpm, which is already available in the updates repository. A simple "yum update" will grab it, along with a few other things. It did not work at first, nor with just restarting the x server, but a full reboot fixed it and it seems to be working nicely. Hooray for open source! 48 hours from problem to solution. :D
