I've recently written a bit about my difficulties using UbuntuOne in Kubuntu Maverick and now again in Natty. The sad part is that a bit of regression testing, and working with our Kubuntu developer could have solved this situation long ago. APIs are supposed to give application developers access, not make that access more difficult. https://bugs.launchpad.net/ubuntuone-client/+bug/369230
Now a related incident has happened: a Canonical uTouch patch to Qt which breaks Wacom tablets. For more on this, see: http://www.valdyas.org/fading/index.cgi/software/krita/no_pressure_in_krita.html.
Thank you to the Koffice people for blogging about this.
ScottK assures me that a fixed package can be found in his PPA: https://launchpad.net/~kitterman/+archive/ppa/ while we try to get the fix properly sorted: https://bugs.launchpad.net/koffice/+bug/762938.
Canonical developers, please do some regression testing against Kubuntu before committing changes.
