Bug 473110

SUMMARY
When I create a new folder inside of an album, either by right-clicking an existing album and choosing "New..." or creating the folder on the filesystem, digikam crashes right after with an assertion failure.

ASSERT: "size == 0 || offset < 0 || size_t(offset) >= sizeof(QArrayData)" in file /usr/include/x86_64-linux-gnu/qt5/QtCore/qarraydata.h, line 59

STEPS TO REPRODUCE
1. Start digikam
2. Create a new album with Ctrl+N and click OK

OBSERVED RESULT
Crash.

EXPECTED RESULT
No crash.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu Lunar
