Version: 2.1.0 (using KDE 4.1.0) Installed from: Debian testing/unstable Packages Compiler: gcc version 4.3.1 (Debian 4.3.1-2) OS: Linux Steps to reproduce (for the crash): 1) make sure you have only *one* download in the list. 2) extend the download in the list to show information 3) delete the download 4) that results in: ASSERT: "extenderIndices.value(extender).isValid()" in file /tmp/buildd/kde4libs-4.1.0/kdeui/itemviews/kextendableitemdelegate.cpp, line 128 Steps to reproduce (to make the info widget stay forever in the listview): 1) make sure you have *two* downloads in the list. 2) extend the second download 3) delete both downloads (Downloads -> delete all finished) 4) the extended info widget of the second download is still there (I'll attach a screenshot). These may actually be two different bugs, but I think they are too much related, that's why I am reporting them in one bug report.
Created attachment 26582 [details] screenshot that shows the extender widget after deleting both downloads
The crash (assert) has already been fixed (not sure why it is not for your, I thought it went into 4.1.0...) We will take a look at the second issue.
These bugs should be fixed at least in trunk.
