** Description changed: - This application crashed immediately when I put in a DVD with region - code 1 in my code 2 laptop and selected "Open with VLC". No idea though - whether the region has any influence on this problem. + [Impact] + VLC (and Totem) crash in dvdnav_describe_title_chapters() when attempting to play DVDs with a different region code than the player, and perhaps under other circumstances. + + [Test Case] + Verify player is set to play one specific region code. + Insert DVD with a differing (unsupported) region code. + Launch VLC and open the DVD. + + [Regression Potential] + This just adds a check that the cell ID is not 0. 0 is not a valid ID. + Upstream reviewed and accepted this patch, so it's had wide testing. + + [Original Report] + This application crashed immediately when I put in a DVD with region code 1 in my code 2 laptop and selected "Open with VLC". No idea though whether the region has any influence on this problem. There was no user input.
