Version: (using KDE 4.1.3) OS: Linux Installed from: SuSE RPMs While I was playing with tab drag and drop I saw two problems that I'm reporting together because I think they are related: If you drag and drop a tab from a konsole window to a konsole window with a split view, the tab is only added on one of the split views, not to both tab lists (of both views). Because of this, you can drag a tab to a split window, then close the split and lose the tab. Additionally (and I think as a side effect of this), if you open a new konsole window, do ctrl+shift+l, drag the tab from the left side to the right side and then do ctrl+shift+s you loose "both" tabs, and get a blank konsole window.
Part of this bug might be related to strange QSplitter behavior, like in bug #190265.
