I get the same crash after trying this. I went from stable release suffering the problem. I changed my repo to unstable to install nuvola-flashplugin, upgraded nuvolaplayer to the current unstable, applied the env's using export and ran nuvolaplayer -D. The client launches, and gets to perhaps 20% of loading the Google Play library before the crash. I also ran the same build of nuvolaplayer with the same command from another shell (so no env's) - this still launches and still suffers the same "wheeling" issue on playback as before. nuvolaplayer -D Nuvola Info nuvolaplayer.vala:147: Welcome to Nuvola Player Unstable, development version: 2.1~r729.unstable Nuvola Info nuvolaplayer.vala:149: Revision: 729,
