Description Jaap Kroes 2007-02-09 17:09:15 UTC

Version:           1.4.5 (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages

Amarok Suddenly crashed when selecting a song to play, on my kubuntu feisty fawn (alpha version), I compiled amarok from source with MTP-support.
Before it crashed it had been playing for almost 6 hours non-stop without crashing or anything, I've not been able to reproduce this error.

Comment 1 Lydia Pintscher 2008-06-16 00:56:33 UTC

Amarok 1.4.x is in bugfix-only mode as development is focused on Amarok 2. Unfortunately your bug will very likely not get fixed, as the risk of regressions is too high and the Amarok developers do not have the resources for it. Thank you for your report though. Please don't hesitate to report new bugs should you have any problems with Amarok 2 once it is released.
