Created attachment 62743 [details] New crash information added by DrKonqi nepomukservicestub (0.2) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2 - What I was doing when the application crashed: Using kubuntu normally. Usually it breaks when editing pictures in Digikam (I have set that metatags will be stored as file's metadata). - Unusual behavior I noticed: Nothing uncommon. - Custom settings of the application: Nothing uncommon, a part that I updated KDE to 4.7 and that's when all the problems started to happen. -- Backtrace (Reduced): #9 0x00007fdd74d59a8f in malloc_printerr (av=<value optimized out>, p=0x262f9f0) at malloc.c:6283 #10 _int_free (av=<value optimized out>, p=0x262f9f0) at malloc.c:4795 #11 0x00007fdd74d5d8e3 in __libc_free (mem=<value optimized out>) at malloc.c:3738 #12 0x00007fdd771f07a5 in ~QVector (this=0x262e820, __in_chrg=<value optimized out>) at ../../include/QtCore/../../src/corelib/tools/qvector.h:119 #13 ~QObjectConnectionListVector (this=0x262e820, __in_chrg=<value optimized out>) at kernel/qobject.cpp:262
