 Hello,

 KProcess guru needed. I have problem when using kstart : It uses 
KProcess:start( DontCare, NoCommunication ). The problem is that every KDE 
app here prints a warning about no definition of PluralForm ( the new i18n 
thingy, it's not handled in kde-i18n-cs yet ), but since it's a background 
process when started using KProcess, it gets SIGTTOU when trying to print the 
output and it's simply stopped.
 Just setting it to SIG_IGN for SIGTTIN and SIGTTOU makes it work, but now it 
prints the output to console, which is probably a thing that processes 
started from KProcess shouldn't do. Just closing fds 0, 1 and 2 doesn't work, 
so what's the proper way of getting rid of the output ? Is something like 
dup2( open( "/dev/null", O_WRONLY ), STDIN_STDOUT ) ok ?
