Yes, there is currently a strange problem with gcc optimization in usermode. Currently, one can either remove package "usermode", so that console authentification will fallback (and it works) and launching programs like userdrake (from console!) is possible again. Rebuilding usermode with -O1 also apparently workarounds the problem. Gwénolé our gcc master planned to look at this problem and fix it, shortly. -- Guillaume Cottenceau - http://people.mandrakesoft.com/~gc/

Wrong.
from 'strace -f':
[pid 10885] execve("/usr/sbin/userhelper", ["/usr/sbin/userhelper",
"-d", "5,4,2", "-w", "mcc"], [/* 50 vars */]) = 0
[pid 10885] write(2, "userhelper must be setuid root\n", 31userhelper
must be setuid root ) = 31
[pid 10885] _exit(6)
The interesting thing is that userhelper *is* suid root.
Sorry for the very inacurrate original post on my part.

Wow, it dies right after receiving an answer from the font server
apparently. A backtrace didn't seem to give much more info than that
either:
Core was generated by `userdrake'.
Program terminated with signal 11, Segmentation fault.
#0 0x40120d89 in ?? ()
(gdb) bt full
#0 0x40120d89 in ?? ()
No symbol table info available.
Cannot access memory at address 0x0
Not much there to work with :(
