The crashes seem to be in the metabar plugin. I don't believe we ship it, or do we?
Um....I don't know. Apparently the metabar is "shipped" with Konqueror (at least in FC6+extras/updates), because I do not remember specially adding it. Konqueror is part of the "kde-base" package in FC6 - it is not a separate package - and I assume the output above is from the kde-base-debug package, which is installed on this box. The metabar is the only sidebar I use - I have only briefly played with the others, a long time ago. However, I also remember having to add other packages in the past - kde-3.4.1-1.0.noarch (KDE "Virtual" container package)???, kde-filesystem ???, can't remember exactly what/when - to get other stuff to work (install-for-dependencies), plus I've piled on all the extras available :-)

OK, so the debug packages were not installed on this machine. Now they are, if that helps when the next crash happens.
Created attachment 20486 [details] Latest crash "dump" report, with debugging active.
It seems you don't have installed all debug packages. E.g. kdelibs and kdeaddons seems missing. But more important: How can you reproduce it ?
I can reproduce it: I look at /tmp and press reload a few times (selecting some items inbetween, changing from treeView to iconView mode)... Running this in valgrind reveals, that it might be due to the fact that the MetabarWidget contains a member currentItems which does (line 189) currentItems = new KFileItemList(items); which produces a shallow copy of the item list (only pointers are copied). And at some point kdirlistercache is deleting the KFileItem but currentItems still points to it ...
