It seems other people are having this same issue. As reported, the web-admin crashing issue does seem to be a 64-bit issue. I’m having this issue as well. Here are my specs:
Specifics:
64-bit Ubuntu Dapper Server
Linux [HOSTNAME DELETED] 2.6.15-26-amd64-server #1 SMP Fri Sep 8 20:33:15 UTC 2006 x86_64 GNU/Linux
Aside from this minor issue, 1571 works well.
