Bug 424393

SUMMARY
First run of Elisa, it successfully imported 499 music files from $HOME/Music.  The Albums view was the default view.

I attempted to scroll down to view more albums, and Elisa immediately crashed:

ASSERT: "phase == Startup" in file qml/qqmlobjectcreator.cpp, line 161

I can reproduce this crash every time.  Running Elisa inside GDB allows the second page to be displayed, but the third page still crashes.

STEPS TO REPRODUCE
1. Open Elisa.
2. Scroll the Album view.

OBSERVED RESULT
ASSERT: "phase == Startup" in file qml/qqmlobjectcreator.cpp, line 161

EXPECTED RESULT
Albums displayed.
