I have found this

socket(PF_UNIX,SOCK_STREAM,0) = 5
connect(5,unix_addr.sun_path=/tmp//kfm_1002_1068BRAMSCHE_0.0,size)=okay
...
later
....
newsock = accept (sock, (struct sockaddr *) &clientname, &size))
Error accepting (UNIX) sock = 5 new_sock=-1 errno=113

It is curious, that if starting this app (kpanel) like below, no errors
occurres.

 	strace kpanel >/dev/null

It seems to me, that there are some correlations between strace printing
code and functionality of some cygwin_accept() sub functions. Perhaps some
statements are only executed while stracing.

If you need some additional informations tell me and I will look.

Regards
Ralf
