SVN commit 1115784 by mwiesweg: Set flags to false when info is updated. Some restructuring, disentangle locks. CCBUG: 234594 M +45 -43 tagscache.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1115784 I have changed a bit here and there, but I'm not sure about this crash. Is any other thread involved as well? Is this really the thread where the crash hit? I only have 2 threads : * 2 Thread 0xb15b9b70 (LWP 13709) 0xb5211095 in QMutex::lock() () from /usr/lib/qt4/libQtCore.so.4 1 Thread 0xb2cde720 (LWP 13705) 0xffffe424 in __kernel_vsyscall () The second one : #0 0xffffe424 in __kernel_vsyscall () #1 0xb4f45ca7 in poll () from /lib/libc.so.6 #2 0xb4998cbb in g_poll () from /usr/lib/libglib-2.0.so.0 #3 0x0000000a in ??

Version: SVN r1115586 (using KDE 4.4.2) Compiler: gcc version 4.3.4 (Gentoo 4.3.4 p1.0, pie-10.1.5) OS: Linux Installed from: Gentoo Packages Digikam crashes at start when scanning for new images, or if there is some modifications on the hdd. I traced it back to "libs/database/tagscache.cpp" l77 I noted the existance of some booleans like "needUpdateInfos" and "needUpdateHash" that where never put to false, even after an update. So i added "needUpdateInfos = false;" line 79 and "needUpdateHash = false;" line 94. Anyway the crash moved to an other function.
