an example of the file "chinese converted"

Problem description: 
I'm converting traditional Chinese words into simplified Chinese in a 50MB txt, and I split it into 59 pieces using Textforever, 1MB per file. I each open the txt in libreoffice writer of the version mentioned above and click "tools --> language --> chinese conversion". It acts well at first, using about 45MB RAM. After conversion of a txt finished, I close the file and open another. Then when the number of the files that had been converted accumulates up to 5 or more, I noticed in the KDE System Guard(ksysguard)  that libreoffice is consuming about 825MB RAM (soffice.bin). And as my computer has only 1 GB RAM, both the system and libreoffice UI is responding rather slowly. But the latter can still convert my file at a slower speed. My processor is AMD Athlon dual core 64 and runs KDE smoothly.

additional information:
Then I have two choice. One is to quit libreoffice. But ksysguard shows SOFFICE.BIN is still running in the background, taking as much RAM as it does before libreoffice quits. So I have to end the process manually every time. The other is continue using libreoffice. But I often end up pressing "CTRL+ALT+BACKSPACE" to kill xserver because I can't see any responding on my desktop and libreoffice.

In fact, I don't know whether it's a problem of libreoffice or one of the Chinese conversion module. And I even disabled libreoffice's JRE but nothing turns better. My install way is to pick up official rpm in your website and run "rpm -i *.rpm", and earlier I have removed the openSUSE's libreoffice package 4.1.

  I'm not a English speaker and may not describe correctly. I hope you find out the bug. And I knows little about bug-reporting.             
Operating System: openSUSE
Version: release

I couldn't reproduce this on LibreOffice or 4.4 master
Could you possibly update your LibreOffice and try again?
