Confirmed. I happened to stumble on this bug on my own. Exacts steps to reproduce - 1. Open the "Edit Tags" dialog 2. Click on the 'X' to delete a tag, and donot move your mouse at all. 3. Press Alt+D ( The shortcut to confirm deletion ) 4. Without moving the mouse, click on 'X' again. I've looked at the code, and I'm not sure I can easily produce a simple fix. The problem is that m_deleteCandidate is not set since it is only set on mouse move events. Either way this code is very old, and should be using a proper asynchronous model.
Git commit c8fcee890200f39993b2131d0ac3697d5fddcf4d by Vishesh Handa. Committed on 29/07/2011 at 14:13. Pushed by vhanda into branch 'KDE/4.7'. Allow deletion of multiple tags without moving the mouse The dialog used the mouse move event to sent the m_deleteCandidate, and then set m_deleteCandidate = 0. On trying to delete the next tag, the deleteTag() function would assert as m_deleteCandidate was 0 m_deleteCandidate is now set to next tag after deletion of a tag.
