Hi Dev,

I had 4 random panic since last friday, 2 using "soundbird", 1 with "soundbird" and "fuse" (ZX spectrum emulator), and 1 (the last one that panic info refers) with only "pidgin", and few minutes after recover from last panic, all on gnome 2.22 environment, and with always with "pidgin" in use, only fuse is compiled with oss remain apps are using sada via oss. Any test you need please just ask.

I notice this message in "/var/adm/messages" also:
