Description Eric Runquist 2011-12-14 05:32:41 UTC

Application: amarok (2.4.3)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
New install of Amarok via Ubuntu Software Center on Ubuntu 11.10. First time I launched Amarok it crashed, and has crashed every time since. I see the splash screen for a few seconds, then it dies.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

iPod handler: do not crash when master playlist is null

This is a late fix for bug 288936. I've added i18n( "Unknown" ) during
string freeze, but this exact string is already used elsewhere.

Sorry for such a last-minute commit, but this was an easy crashfix.

BUG: 288936
FIXED-IN: 2.5

Comment 3 Matěj Laitl 2011-12-14 11:01:54 UTC

Thanks for your report, Eric. This crash should be fixed in Amarok 2.5. (to be released in a couple of days)

However, if your iPod is named "Unknown" in Amarok 2.5 or if you have other problems with it when you'll test with the newest Amarok release, please reopen this bug.
