I am able to reproduce this bug on maverick.

To reproduce:
echo 1 | sudo tee /proc/sys/kernel/yama/ptrace_scope 

(this is the default in Ubuntu 10.10 AFAIK)

The following message shows up in dmesg:
[ 1994.869982] ptrace of non-child pid 8718 was attempted by: wineserver (pid
8543)

Workaround:
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
