Hello, staff. I'm a ArchLinux user. I download swt.jar, put it into Djvu2Pdf/lib dictionary and run as root. I do everything as this site said.

But I just get an error message like this:
Invalid MIT-MAGIC-COOKIE-1 keyException in thread "main" org.eclipse.swt.SWTError: No more handles [gtk_init_check() failed]

at org.zefer.djvupdf.DjvuConverter.main(DjvuConverter.java:158)

Can you help me run Djvu2Pdf? Thank you!

BTW: I tried swt-3.6.1-gtk-linux and latest swt-3.6.2-gtk-linux, both can't work. I run pacman-Q jre, get jre 6u24-2. I run pacman -Q gtk2, get gtk2 2.22.1-1. I hope those message will be helpful.
