The problem is not just over krusader. It affects all KDE apps. I had the same error for amarok, kile, konsole etc.

IF YOU WANT TO SEE DEBUGGING INFORMATION, PLEASE USE: ** ** amarok --debug ** ********************************************************************************************** The program 'amarok' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 3663 error_code 3 request_code 20 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) ** Also affects: krusader Importance: Undecided Status: New ** Project changed: krusader => amarok -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1197879 Title: krusader crashes with BadWindow - invalid Window parameter To manage notifications about this bug go to: https://bugs.launchpad.net/amarok/+bug/1197879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
