Status changed to 'Confirmed' because the bug affects multiple users.

The Bug reporting software shows me that the bug that happens after every login is a duplicate of http://bugs.launchpad.net/bugs/1701932 - but there is no bug on this address!

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 1432137, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

I also get this error message

Xorg.assert.failure:Xorg: ../../dix/privates.c:385: dixRegisterPrivateKey: Assertion ‘lglobal_keys[type].created‘ fails

But the error reporting software tells me that the bug is a duplicate of https://bugs.launchpad.net/bugs/1629678 which also does not exist, but here it is a different one than told above.

BTW: Is there a way to catch the error report sent in. It is very tedious to retype what I can see when I inspect on what the error reporting software sends in.
