dmesg error about pthreads

[Kevin DeKorte]

On my FC1 system with the latest patches I'm getting this in the dmesg log. 
Been getting them for awhile.

application bug: wine-pthread(4537) has SIGCHLD set to SIG_IGN but calls 
wait().
(see the NOTES section of 'man 2 wait'). Workaround activated.

wine -v
Wine 20031212

Is this anything I need to worry about
