Yeah, by "reproduce the problem" I meant starting users-admin. But don't
worry, I think I've found the problem. The UID we found out thanks to
your debugging was 140733193389032, whose hexadecimal representation is
0x7FFF000003E8: if you only keep the lowest 8 bytes, you get 0x3E8,
which is 1000 in decimal. So that means the code is wrong and doesn't
work on 64 bits CPUs: garbage appears on the second half of the number.
Looking at the code in liboobs, I could check that this part is the only
one which doesn't copy the UID/GID to a guint32 before passing it to
dbus_message_append_args(). Instead, it passes directly an uid_t
integer, which is likely to be only 32 bits on every architecture. These
games with integer types are quite complex!
Much thanks for your help, I'll try to check on a 64 bits machine that
this fix actually works, and push it before we release the next version.
Please continue testing the gnome-system-tools in Lucid to get them as
bug-free as we can!
