+Description:
+ QPainter together with QPrinter leaves a lot of temporary files in
+ /tmp with every printout. That is a problem for embedded devices,
+ which have not such a large /tmp-partition. We are using 80 MByte as
+ tmpfs, i.e. in RAM. After some printounts cups deactivates the printer
+ because there is no space to copy the temporary files to /tmp.
+
+ What happened: In QPdfBaseEnginePrivate::openPrintDevice() noone
+ remembers the file descriptor opened by tempFile() which is a call to
+ the cups library to cupsTempFile()
+
+ Later in closePrintDevice the check for fd<0 fails, so no one closes
+ the file descriptor. If you later remove the file, the descriptor is
+ still open and cannot removed until you close the application.
+
+ If you print 20 times and more during your application is running and
+ you print out large files (complicate forms with a lot of elements
+ produces files with 3-4 MByte) your temporary file can be full, but
+ you don't see (with ls) files in it.
