robin0800, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue in a supported release, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hello Customer

Everyone will notice your new expensive-looking watch, but nobody will find out that it is a replica watch. Designed as a genuine one to the tiniest detail replica watch differ only in price.
Why spend thousands of dollars on the real deal when a replica watch looks so much alike that only an expert could tell the difference...

---------------------------------------
As requested, I just want to verify that I have finally received my package, and I must say it was well worth the wait! Thanks for such a high quality product! I look forward to conducting business with you again in the future.
Bless
