I'm getting something similar when running openoffice.org in ubuntu 8.04 AMD64:
Locking assertion failure.

It will also provoke other bugs such as oo.org impress in fulscreen staying behind the gnome panel 2. Create a new user account and run oo.org. It will run fine on my machine, even with openoffice.org-gtk package installed. 3. Run as sudo I know this should not be done, but for testing purposes, I tried it and it worked flawlessly... Any better solutions? -- hardy, locking assertion failure, xorg/libsdl https://bugs.launchpad.net/bugs/185311 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
