gam_server eats all the RAM slowly

Today I've noticed that my laptop was acting sluggish, and half of the swap
space was eaten. I discovered that gam_server took over 400 megs of virtual
memory, killed it, and went back to work. A few hours later I noticed the same
thing (gam_server eating 500 megs this time), and killed it again. gam_server
started growing again.

To summarize: whenever I kill gam_server, it respawns and starts allocating
memory at the rate of about 0.1 meg per 3 seconds (according to
gnome-system-monitor). I had never encountered this before today.

gdb doesn't help mutch (I get a lot of question marks). ltrace/strace show a
lot of activity -- stating a bunch of files, watching /etc/mtab, writing to
pipes, calling strange numbered syscalls 292 and 293 (I guess strace/ltrace
doesn't recognize inotify?).

ltrace -c -S -p `pidof gam_server` for a 10-second period shows

   20116 calls to g_free
   16457 calls to g_strdup_printf
    3324 calls to g_strdup
    3187 calls to g_malloc0
      90 calls to g_malloc

and a bunch of other calls that don't seem to be related to memory management at
first glance.
