Comment 93 for bug 185311

I had the same problem on Kubuntu 8.04. I am running a AMD64 laptop with an nvidia card. I have installed the proprietary nvidia software which is distributed through its website.

The June 18 download of Openoffice crashed with the "Locking assertion failure" error.

I had previously been running NVIDIA-Linux-x86_64-100.14.19-pkg2. The problem resolved itself when I installed the newer
NVIDIA-Linux-x86_64-177.13-pkg2.run. (There were compile problems compiling the prior nvidia distributions).

Now, the only remaining problem is what on exiting, openoffice ends with the kde crash manager advising of the signal 11 which terminated the process. This is annoying, but openoffice is now usable.
