           Summary: 10 - 20 second lockup (not only) by opening kde dialogs
           Product: kde
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs kde org
        ReportedBy: swalko12 gmail com


Version:           4.0.0 and 4.0.1 (using KDE 4.0.0)
Installed from:    Gentoo Packages
Compiler:          gcc-4.1.2 qt-4.3.3
OS:                Linux

In KDE 4.0.0 and 4.0.1 most times when i open dialogs, parent application and dialog stop responding for 10 - 20 seconds, after then application normally respond and i can work again. This bug is nicely repeatable by opening Dolphin and trying to delete some folders. Same lockups sometimes occur by working in konsole and using auto-completition feature.
