Comment 1 Myriam Schweingruber 2010-01-30 15:55:30 UTC
This looks more like a Qt bug. Could also be related to a buggy glibc, though.

Please upgrade to Amarok 2.2.2 (http://kubuntu.org/news/amarok-2.2.2) and get a newer glibc (available in the karmic-proposed repository, the package you need is called libc6 2.10.1-0ubuntu16).
Comment 2 Myriam Schweingruber 2010-02-27 11:30:35 UTC
Closing for lack of feedback. Feel free to reopen this report if you can
reproduce it with the upcoming Amarok 2.3
