Afaics this is a consequence of the 'fix' that was applied for bug 634678, the regression is also visible in the title/subtitles in normal app detail screens.

Ah, I see, this is a general problem with the title generation for non-application packages. Ok, resummarizing.

The linked branch should take care of the issues listed in this report (see attached screenshot below). Further details can be found in the merge proposal.

Hi. I see that on irc there was a slight discussion as to what was causing this. The specific issue that is causing the wrong title/subtitle in the appdetailsview and for the addons is the change to softwarecenter/db/ at . The revision caused get_appname() to return an appname even when there is no appname. The code in softwarecenter/db/ relies on get_appname returning None when there is no appname. I have fixed get_appname() to return None in my branch, which will restore the correct title/subtitle and addon names in the appdetails view.

The issue with the wrong name in the navigation bar was there before the revision mentioned above and is still present after the change I've just made. Cheers.

Hi kiwinote! Yes, thanks, I noticed that broken return of None and had fixed it in my branch linked above. Sorry, it appears we double-debugged it! :)

Indeed, it was part of my checkin as you referenced above where the regression crept in. Doh!

In any case, I've simplified and consolidated the code in the attached branch and wired all of the places in the UI that displays title and summary to use a single point of origin for this info. Hopefully this will take care of it for good (it appears to work well in my testing). If you have time, I'd certainly appreciate your taking a look at the proposed merge to see if there's anything I missed.

Hi Gary!
Eugh, sorry I didn't notice that you had already fixed that in the branch!
Anyway, I've tested the branch and made a few changes so it works well with apturls/deb files as well.
The rest all looks quite sweet :)
Thanks for your work on this!
