Application: dolphin (2.0.95) KDE Platform Version: 4.8.3 (4.8.3) Qt Version: 4.8.2 Operating System: Linux 3.2.0-24-generic x86_64 Distribution: Ubuntu 12.04 LTS -- Information about the crash: - What I was doing when the application crashed: I started dolphin. The main winow was visible a brief moment (the places panel was filled with correct data, i.e. my devices, the searches thing, places etc) and then it crashed. This is now for over a week now. (Using project neon KDE master compiles, it says 4.8.3 because I was actually running it from KDE 4.8.3 but it also does not work when run from Project Neon) The crash can be reproduced every time. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

*** This bug has been marked as a duplicate of bug 268064 ***
The same crash occurs recently with all other applications that access KServiceTypeTrader::defaultOffers() and is unrelated to Dolphin. I did not bisect the guilty commit, but probably it is located inside kdelibs (I'm currently working with an older version).
