New crash information added by DrKonqi

dolphin (1.7) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

- What I was doing when the application crashed:
I was pressing ctrl-tab several times in a row. I'm not sure if it crashed
after I reached the last tab or the first tab again, but I am now able to
reproduce with 100% success (5 out of 5 attempts).
From the six dolphin windows I had from the session load, three crashed by
alt-tabbing, and three don't crash, one of them with four tabs open.

Method:
    open a new dolphin window, hit ctrl+t three times, then hit ctrl+tab two
times.
Result:
    three new tabs are open with the focus on the last tab, than focus transits
to the first tab, and then to the second, immediately followed by a crash.

Hope this helps.
