[Bug 186255] New: digiKam crashes when switching collection database

https://bugs.kde.org/show_bug.cgi?id=186255

           Summary: digiKam crashes when switching collection database
           Product: digikam
           Version: 0.11.0-svn
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.11.0-svn (using 4.2.1 (KDE 4.2.1), Arch Linux)
Compiler:          gcc
OS:                Linux (i686) release 2.6.28-ARCH

This is only true for 0.11!

If you start a "find duplicates" or "find similar" search and change the
database location in the setup dialog, digiKam crashes.

To reproduce:

1. start "Find Similar" for an image
2. when in "Find Similar" view, goto configure dialog
3. change the database location to another digiKam db path
4. You will be asked if you want to use the existing db, choose yes
5. Now digiKam crashes.

In trunk (0.10) it is working fine.
