When running the command net useridlist on maverick 10.10 running samba 3.5.4 it crashses. I have attached the gdb backtrace to this bug report.

Just tried with master -- worked. Can you please upload a valgrind log running that command?
Tried with 3.5.4 as well. Works fine for me. I think I really need a valgrind trace.
