           Summary: Renaming like crasy with F2 slows down my system!
           Product: digikam
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: alexandreracine gmail com

Version:           0.9.2-final (using KDE 3.5.6, Kubuntu (feisty) 4:3.5.6-0ubuntu14)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.20-16-386

Following my latest crash report bug #143200 , it does not crash anymore, but is slow and use a lot of CPU.

How to reproduce:

Focus on one picture and do something like this:
F2, paste (Ctrl+V), enter, [the focus change to the next picture], F2, paste, enter, rince and repeat.

What happens?

100% use of CPU for the next 1 second for the first picture, after that the time seems to grow at 100% exponentially and eventually digiKam does not respond very well (since 100% of the CPU is used). From picture two, it seems like digiKam is trying to do two things at a time or more, probably updating is database, renaming and reworking the thumbnail?

Some facts :

-The folder where the album reside is 17136 elements with 23,7GB total size.
-$ cat /proc/cpuinfo = Model name      : Intel(R) Pentium(R) 4 CPU 2.60GHz
-$ cat /proc/meminfo = MemTotal:      2075540 kB
-In top:
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
30939 XXXX   23   0  170m 120m  31m S  0.0  6.0   1:10.25 digikam        
-The digiKam database is 3MB (If this is indeed the digikam3.db file in the album folder)
