Tim, With a full clean rebuild last night, I now see the following messages in xsession-errors log: tdeioslave: ####### CRASH ###### protocol = pid = 29858 signal = 11 /opt/trinity/lib/libtdeio.so.4(_ZN5TDEIO9SlaveBase15sigsegv_handlerE i+0xd0)[0xb742f350] tdeio_media [tdeinit] media /dev/shm/tdesocket- root/tdelauncherM6C(_ZTI15TQPtrCollection+0x0)[0x8057564] The pid changes but the remainder of the message string remains the same.
