           Summary: digikam 100% CPU on exit
           Product: digikam
           Version: 1.0.0
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: msp at debian.org


Version:           1.0.0 (using 4.3.4 (KDE 4.3.4), Debian packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.32-trunk-686

When I exit digikam normally, CPU goes to 100%, on every exit.

The application appears to close normally from the GUI, but it is still running
in the background at 100% CPU

A strace reveals the following:

futex(0xa393bc2c, FUTEX_WAIT_PRIVATE, 1, NULL^C <unfinished ...>


The futex just sits there and does not finish correctly.

The "^C <unfinished>" only appears once I kill the process manually after a few
minutes.

This could be related to bug 218467, however I do confirm I have all nepomuk
services off.
