Below is a gdb bt from a segfault provoke by my vignette for dse2. This seems to
be relatively reproducible in the sense that I got a segfault three times
(without gctorture) on Mandrake 9.0 and also caught it in Mandrake 9.1, at what
looks to my untrained eye to be about the same place (actual at
connections.c:293 in Mandrake 9.1). This is the build from Friday morning.
