           Summary: krunner crashes from time to time
           Product: krunner
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: amantia kde org


Version:            (using KDE Devel)
Installed from:    Compiled sources

KRunner crashes from time to time, as I saw especialy if you execute commands that are not recognized by it from .desktop files (eg. nvidia-settings, kicker from KDE3, own shell scripts). It doesn't always happen.
Here is the BT:
