New crash information added by DrKonqi

dolphin (1.99) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4

- What I was doing when the application crashed:

I'm able to trigger the crash always when toggling Alt + . several times in a row (3-4 times).

Comment 2 Chirag Anand 2011-09-24 20:59:22 UTC 
I am not able to reproduce it with the current master. I tried these steps:
- Create a new folder, and open it
- Remove it via terminal
- Press 'alt + .' again and again
- Go back and forward.

Nothing happens.

Please correct me if I need to do something else to reproduce it.
Comment 3 Hrvoje Senjan 2011-09-24 22:16:15 UTC 
Alt + .
Refresh (F5)
And then pressing Alt + . 3 times
Comment 4 Hrvoje Senjan 2011-09-25 08:40:26 UTC 
Anand, i've made a video of what triggers the crash:

Dolphin_kcrash

Thats the behaviour with kde-baseapps compiled against 4.7.1 kdelibs/runtime/workspace. Kde-baseapps compiled against master has a different behaviour - if previews are turned on, then it crashes after (i'm attachint the backtrace of this):
Alt + .
F5
Alt + .
If previews are turned off , i also can't reproduce the crash.
Comment 6 Chirag Anand 2011-10-31 08:58:06 UTC 
[The video isn't present there any more].
I am running the same version, but still can't reproduce this (with previews enabled). May be someone else needs to look at it.
Comment 7 Hrvoje Senjan 2011-10-31 10:53:28 UTC 
I also can no longer reproduce this.
