Thanks for the bug report! Did you press Alt-Tab to switch to Kate during the drag and drop operatrion and do you have Desktop Effects enabled? In that case, this is probably bug 200583. Otherwise, this is probably bug 203887. Unfortunately, it seems that the cause of both of these issues is still unclear.
You are welcome! Right, I tend to maximize my windows so I am using Alt-Tab probably always with Drag&Drop. Can I improve the debug data somehow? I am using Gentoo.
Thanks for the quick reply! (In reply to comment #3) > Can I improve the debug data somehow? The backtrace is (and also the backtrace in bug 200583) is quite good as it is. Unfortunately, I'm not familiar with the relevant code, and I don't know if anything else could be done to help fix this issue :-( *** This bug has been marked as a duplicate of bug 200583 ***
