The following behavior started after upgrade to Digikam 4.3.0. Earlier version did not show this behavior.

Variant A
1. Start Digikam
2. Add an XCF file created with GIMP 2.9 to any folder within your Digikam collection
3. Digikam crashes

Variant B
1. Place an XCF fiel created with GIMP 2.9 in any folder within your Digikam collection
2. Start Digikam
3. Digikam starts and then crashes immediately


Reproducible: Always
