[Bug 177009] New: digikam eats all CPU when Restore plugin is selected

http://bugs.kde.org/show_bug.cgi?id=177009

           Summary: digikam eats all CPU when Restore plugin is selected
           Product: digikam
           Version: 0.10.0-beta6
          Platform: SuSE RPMs
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0-beta6 (using KDE 4.1.3)
Compiler:          gcc-4.3-39.1
Installed from:    SuSE RPMs

A Canon RAW (.CR2) image is imported OK. Then the Restore plugin is invoked.
Immediately both CPUs (AMD Athlon 64 X2 4200+) are eaten up at 96-99% each,
even after cancelling the plugin dialog. Of course the user interface becomes
terribly slow thereafter. Sometimes (quite difficult to reproduce) digikam even
hangs.

The distro is openSuSE 11.0, kernel 2.6.25.18-0.2-pae. digikam has been
installed from repositories, automatically resolving package dependencies
(libkdcraw, libkipi, and kipi-plugins). No crashes nor tracebacks :-( but, just
in case, the debug packages are installed. I have only the standard output
available (not really very helpful):

This is the problem. Something have been broken in code during EditorTool
porting. I will fix it.
