This bug is most probably already fixed in trunk. If you can verify, we could also backport it to the KDE 4.1 branch. SVN commit 858415 by ahartmetz: - Do not treat about-to-be-deleted extenders as still present, hopefully fixing hard to reproduce bugs in KGet. - Properly document that the delegate takes ownership of extenders. Hi, regrettably the current kdelibs SVN checkout fails to compile on my machine. So currently I cannot verify if this bug is still valid in trunk. However, if I manage to compile some trunk version in the future I'll see if this bug is still valid (and if so, I'll just reopen this one) Hi, not sure if it is still helpful, but I just wanted to say that this bug indeed seems to have been fixed in trunk (perhaps by commit 858415). So backporting that fix might be a reasonable idea.

Version: 2.1.1 (using 4.1.1 (KDE 4.1.1), Gentoo) Compiler: i686-pc-linux-gnu-gcc OS: Linux (i686) release 2.6.25-gentoo-r7 Today I downloaded two files with kget. After both downloads were finished, I selected the first one by clicking on it (it expanded) and then selected the second one by hitting shift+down. KGet from KDE-4.1.1 then crashed with the backtrace below. Regrettably I am not able to reproduce this crash.
