I thought about reporting a bug about a package from the wine PPA, but neither https://bugs.launchpad.net/~ubuntu-wine has an option to post a new bug report no https://answers.launchpad.net/~ubuntu-wine has an option to post a new question. But there are old bug reports and questions listed there.
I wonder how I can do this.
The standard ubuntu-bug
way doesn't work for a package from PPA:
$ LC_ALL=en_US.UTF8 LANGUAGE=en LANG=en_US.UTF8 DISPLAY= ubuntu-bug wine1.7
*** Collecting problem information
The collected information can be sent to the developers to improve the
application. This might take a few minutes.
............
*** Problem in wine1.7
The problem cannot be reported:
This is not an official Ubuntu package. Please remove any third party package and try again.
Press any key to continue...
No pending crash reports. Try --help for more information.
$
ubuntu-bug <name-of-package>
