There is a variety of burg-* packages on AUR:
the packages with *-fixed postfix are the working ones (There is a thread
going on https://bbs.archlinux.org/viewtopic.php?id=100130). And the other
packages (the packages other than burg-themes-extras, I didn't test it) are
orphaned or not working -BTW, most of them aren't updated for a while-. I
suggest removing burg-bzr, burg-themes and renaming fixed packages as
And also, I'll test burg-themes-extras and let you know if it works.
