Description Gerd Grass 2013-04-29 22:41:27 UTC 
Application: konqueror (4.10.2 "release 1")
KDE Platform Version: 4.10.2 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.1-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
I startet a new konqueror window.
I changed the folder (not my home directory but 2 folders below).
When running the mouse over the folder items (without any clicks) then konnqueror crashes (not for 100 % reproducable but happens quite often)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Simeon Bird 2013-09-11 06:16:31 UTC 
This looks like a problem due to konqueror linking against the old version of nepomuk in kdelibs, and the FileMetaData widget linking against the new version. 

Not much we can do about this until konqueror links against the new version in nepomuk-core, I think, sorry.
Comment 2 Vishesh Handa 2015-01-23 16:22:14 UTC 
Thank you for taking the time to file a bug report.

The Nepomuk project is no longer included in the KDE Software Compilation. With Plasma 5, we have replaced most of the underlying technology with Baloo and other components. Hopefully this will have addressed your concern.

We encourage you to try out Plasma 5 (+Baloo) and let us know if your problem persists.
