Hi,

amarok reproducably crashes when you click multiple times on the "new folder" icon in the podcast panel. select one of the newly created folders and then click again the "new folder" icon. switching between these two actions will sooner or later cause a crash. See the attached stacktrace. if you have questions, please ask.

Reproducible: Always




Stacktrace:
