[Bug 171318] New: Digikam backend does not exit on Quit - processes hang

http://bugs.kde.org/show_bug.cgi?id=171318

           Summary: Digikam backend does not exit on Quit - processes hang
           Product: digikam
           Version: 0.10.0-beta3
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0-beta3 (using 4.1.2 (KDE 4.1.1 (KDE 4.1 >= 20080828))
"release 52.1", KDE:KDE4:Factory:Desktop / openSUSE_11.0)
Compiler:          gcc
OS:                Linux (i686) release 2.6.25.16-0.1-default

Starting Digikam and pushing "Quit" from the "Album" menu quits Digikam only
visually, the processes initiated by Digikam remain hang. If I start Digikam
from a terminal and push "Quit" there's no finishing to see.

`ps auxw|grep digikam` gives me an output like this:

not changing even after a few minutes.

'killall digikam'
quits the first of the above processes '/usr/bin/digikam', only, the two KIO
processes remain hanging. Seems to be a synchronizing problem and hang in the
KIO process.

... update: after several minutes the kio_digikamd process finished now, too.
Is the solution to wait for this? Are these processes important, what happens
on a shutdown meanwhile killing the kio_digikamd processes before they finish
in their "natural" way?

I noticed that before, too. But now it seems to be solved. For me it happened
most of the time when I switched very fast between albums so that the thumbnail
generation went crazy.
Also "find duplicates" was not stopped properly when closing digiKam while it
was running. There was no cancel action, but I have added this now. Maybe
newest SVN will solve the problems?

KIO slave processes are started and stopped by kdelibs. I think it is normal
behavior that they are kept running for a certain time as part of a process
pool and stopped later.
It would be a bug if they were running and consuming CPU, but I dont think this
is the case.
