Thanks for the bug report! I can confirm this crash. It's somewhat related to bug 308018 - the KItemListRoleEditor (the object which handles inline renaming) gets deleted in a nested event loop which is run inside one of its functions. As soon as we return from the loop, we get a crash. I might have an idea how to fix this.
Git commit 951cb9c35d7a9ef814b3de5b359915968da9b881 by Frank Reininghaus. Committed on 05/11/2012 at 22:03. Pushed by freininghaus into branch 'KDE/4.9'. Prevent crashes caused by nested event loops run when renaming inline When renaming inline and starting a drag or invoking the context menu, a nested event loop will be run. If the role editor loses focus and emits roleEditingFinished(), we must prevent that deleteLater() is called because this would delete the role editor inside a nested event loop which is run from one of its own functions. We would get a crash when returning from that event loop otherwise.

*** Bug 310801 has been marked as a duplicate of this bug. ***
Unfortunately, it still does not always work as expected in KDE 4.9.4 (see bug 311409). Sometimes, the drag does not stop when dropping the text on the Places Panel.
