Hi,
I don't know if I'm doing something wrong but:
qt-x11-4.7.4-2.fc14.i686
After document is printed in /proc/MYPROCESS/fd/ there are orphan symlinks to 
/tmp/cupsXXXXXXX files.  That's fine with me but after it passes open files 
limit (ulimit -n) , my app cannot open any file anymore since number of files in 
/proc/PROCID/fd > 1024 (ulimit -n is 1024 on my machine).
Tried to print with other apps and there's no orphaned files (kwrite, soffice 
etc).

This is example from /proc/MYPROC/fd
lr-x------ 1 linda linda 64 2011-10-17 08:22 12 -> /tmp/cupsa1fKP1 (deleted)

1.QPrinter is created
2.Doc is successfully printed
3.QPrinter is destroyed

What I'm doing wrong ? KDE apps eg. kwrite doesn't have such problems, so I'm 
wondering if I'm doing something wrong ... but using simple case from 
http://doc.qt.nokia.com/4.7/printing.html shows that problem.
