Hello Mario, or anyone else affected,

Accepted mythbuntu-common into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/mythbuntu-common/0.73 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I've validated this one by adding proposed and updating to mythbuntu-common 0.73. Doesn't crash on NV HW anymore.

This bug was fixed in the package mythbuntu-common - 0.73
