[errors.ubuntu.com bug bridge]

The Ubuntu Error Tracker has been receiving reports about a problem regarding unity8. This problem was most recently seen with version 8.01.1+15.04.20141111~rtm-0ubuntu1, the problem page at https://errors.ubuntu.com/problem/1d146aed1a307e6e69dc8cb8f3d7ee012df94e2c contains more details.

To reproduce:

Scroll down the click scope, open the ubuntu store, wait a bit for it to load results. When first results appear, quickly scroll down to the bottom and then a tiny bit back up so that the header appears. Press the back button. It'll crash in most of the cases.

Another ::data that does unbounded checks, i'd say this is the problem.

QVariant
Categories::data(const QModelIndex& index, int role) const
{
    CategoryData* catData = m_categories.at(index.row()).data();

unbounded access i mean

[Albert Astals Cid (aacid)]

Ok, is not that, i just added that check and still got it to crash

Seems this may still be happening in rtm according to https://errors.ubuntu.com/problem/7c52ff86c8dc73d895473731bf95b813de1324ce

Maybe not very important though
