  hum, wrong list, this should go to the xml gnome org one. Could be a
good idea to also double check your subscriptions, I had to manually

  I certainly ran make tests before doing the release, both on Linux i386
and x86_64 and didn't got that problem. The best you can do is run the 
program under valgrind with the --db-attach=yes option and then post the
stack trace you get on the error. Or you can run it directly under gdb
and post the stack trace too.
  I checked this test on really weird architecture like linux/s390 and 
linux/ppc64 and didn't got the problem. I think 2.6.19 is safe to use
but would still like to get more debug informations on that error your got.
