Sentry Crash Report:

Description Daniel Ziltener 2011-03-09 22:49:09 UTC 
Application: dolphin (1.6)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-default i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I right-clicked a file, selected "Properties", then "Informations", then "Settings..." since the "Informations" tab was empty. In the new window, nothing was displayed so I clicked "ok". The window didn't close but instead Dolphin locked up and crashed some minutes afterwards.

-- Backtrace:
Application: Dolphin (kdeinit4), signal: Aborted

Comment 4 Vishesh Handa 2013-01-16 14:15:21 UTC 
This seems like a case where a number of KLoadFileMetaDataThreads were running (Thread 2 - 8) and then another thread (Thread 1) tried to kill all these threads cause the calling widget had now been deleted.

I'm marking this as FIXED cause -
1. The kio FileMetdataWidget doesn't used threads any more. It uses another process which is a lot safer.
2. Dolphin no longer uses the FileMetadataWidget - It now uses the Nepomuk2::FileMetadataWidget which also uses a separate process.
