Hmmm. I also have the same issue on my KDE4 Debian box. The solution is the same : if I input
Code:
export OOO_FORCE_DESKTOP=kde
in a terminal and then run oowriter from the CLI, everything is okay.
I have just been playing on my Debian box and added
Code:
export OOO_FORCE_DESKTOP=kde
to /etc/openoffice/sofficerc and my toolbars work!
edit: I will test on the Slackware box later.
