Created attachment 63885 [details] 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). -- Backtrace (Reduced): #6 operator bool (this=0x40) at ../../kdecore/util/ksharedptr.h:106 #7 KFileItem::determineMimeType (this=0x7fff9990af40) at ../../kio/kio/kfileitem.cpp:696 #8 0x00007f26cfacf307 in startPreviewJob (items=..., this=0x10d1110) at ../../../dolphin/src/kitemviews/kfileitemmodelrolesupdater.cpp:522 #9 KFileItemModelRolesUpdater::startPreviewJob (this=0x10d1110, items=...) at ../../../dolphin/src/kitemviews/kfileitemmodelrolesupdater.cpp:497 #10 0x00007f26cfad1213 in KFileItemModelRolesUpdater::resolvePendingRoles (this=0x10d1110) at ../../../dolphin/src/kitemviews/kfileitemmodelrolesupdater.cpp:440
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.
Alt + . Refresh (F5) And then pressing Alt + . 3 times
Anand, i've made a video of what triggers the crash: http://www.youtube.com/watch?v=zrFqOyCtLRw
Created attachment 63943 [details] 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.
[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.
I also can no longer reproduce this.
