-- Information about the crash:
- What I was doing when the application crashed:
When I tried to import the existing Amarok 1.4 MySQL DB current Amarok app presented following Error: "Could not execute import query: " in the import pop-up window. Trying to understand what exactly is going on as all credentials should be correct I was clicking back and forth and changing the credentials in the hope to get a more informative error message. Then Amarok crashed. As I was running it with --debug flag this is wat was visible in the log:
