unetbootin error:help



new to the forum and a beginner in linux.
so, greetings to all forum members.
need to mount a usb pen with blacktrack .iso image to boot blactrack from the pen. according to what I read, I have to install the UNetbootin, have the image of the o.s. and a USB stick with 2GB.
installed, unetbootin on openSUSE 11.4, which is run on a dell inspiron 1525.
Installation went fine but when I try to run by console (su, password; unetbootin), I get the following error message:
“UNetbootin: symbol lookup error: UNetbootin: undefined symbol: _ZN9QListData11detach_growEPii”
can someone explain to me what it means and how can I solve this problem?
Thank you.
