I had this problem under Solaris 10, although I can't remember which exact release it was. It would have been around July time last year, and every time I ran gaim it would core dump without fail.
I never managed to fix it at the time - I did look at compiling the latest revision from source, but there were a lot of dependencies. I also considered installing from http://www.blastwave.org/
, but didn't, again due to the number of dependant packages required.
If you're happy using the command line, you could look at CenterIM
which has replaced CenterICQ. I've not used CenterIM, but I use CenterICQ on NetBSD/alpha and it's fairly good. The list of requirements for compiling is a lot less than Gaim's was.
However, now it has become Pidgin, there's also a CLI client, called finch I think. You could give compiling that a try - again it'll require a lot less other software to compile.
