Application: dolphin (2.1) KDE Platform Version: 4.9.80 Qt Version: 4.8.4 Operating System: Linux 3.5.0-17-generic i686 Distribution: Ubuntu 12.10 -- Information about the crash: - What I was doing when the application crashed: i copied threee PDF files from external disk to my local hard drive with different permissions in dolphin. I have two dolphins opened - one as normal user and one via konsole "sudo dolphin" command (NOT kdesudo). in root dolphin i fethed three pdf files which were owned by root, group root and copy them in local drive in "non-root" dolphin via right click - copy and right click - pase first file copied succesfully when the other one wanted, the NON -ROOT dolphin crashed. mayi also add that document in his filename was compoed also with russian cyrillic text. when i relaunched NON-ROOT dolphin i saw that all three files were copied succesfully :) but the dr. konqi appeared anway so im sending this error report nice day! Simon :) ps. i use project neon, kde 4.8.90, the newst stuff :) bye The crash can be reproduced every time. -- Backtrace: Application: Dolphin (kdeinit4), signal: Segmentation fault Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

*** Bug 308525 has been marked as a duplicate of this bug. ***
hello! i also would like to add this crash happens ALWAYS if i go int osome random directory and use mouse wheel for scrolling - has to d osth with displaying too many information of subfolders at the same time i think... :) nice day simon
Thanks for the bug report! Considering the backtrace you posted in bug 308524, the slot KFileItemModelRolesUpdater::resolveNextPendingRoles() gets called recursively because it invokes itself using a single shot timer, which expires in Nepomuk's nested event loop. The cause of the crash probably is that the sets m_pendingVisibleItems and m_pendingInvisibleItems and iterators operating on them get corrupted because multiple invocations of KFileItemModelRolesUpdater::resolveNextPendingRoles() try to manipulate them.

This should be fixed by changes in Nepomuk.
