Can confirm 'buggy' behavior here... I'm getting the same issue, I am running Gnome Shell...
In addition to the OP's description.., I also noticed that if I try to re-size a pane (like sliding the playlist pane up into the album covers), this will capture my pointer's state (into the vert. arrows (resize) and once it went to 'grab' hand state) and keep it in this state, preventing me from being able to do anything else, on any desktop in any application (hmmmm) I had even tried clicking on other apps to get focus, even though the pointer indicated that it was thinking something else, and still nothing, which is why...I then have to drop to a terminal (ctrl-alt-f4) and killall banshee to get it all back. The final straw that prompted a web query (and a break from work) and brought me here, is that I tried to open the 'preferences' dialog and it froze....again :) I want it to minimize to the tray, that don't seem to happen either... Don't know if this holds any clues, but Exhaile has exhibited some similar behavior as well.., which is why I tried Banshee again (typically I use Exhaile) Learning my lesson here, not messing with the interface :) Other than not having much of interface functionality...seems ok. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to banshee in Ubuntu. https://bugs.launchpad.net/bugs/878589 Title: banshee interface freezes 2 seconds after first mouse click Status in “banshee” package in Ubuntu: Confirmed Bug description: I just upgraded to oneric and banshee no longer works. 2-3 seconds after the first mouse-click the interface completely freezes. If there is a song playing, it will play to the end but won't progress to the next one. This was working fine a few minutes before I "upgraded". If I run banshee from the terminal: I get the following output: [Info 13:07:08.057] Running Banshee 2.2.0: [Ubuntu oneiric (development branch) (linux-gnu, i686) @ 2011-09-23 04:51:00 UTC] [Info 13:07:09.608] Updating web proxy from GConf [Info 13:07:09.664] All services are started 1.270654 ** (Banshee:2692): DEBUG: SyncDaemon already running, initializing SyncdaemonDaemon object (Banshee:2692): libsoup-WARNING **: No feature manager for feature of type 'U1RequestChrome' [Info 13:07:10.757] AmazonMP3 store redirect URL: https://one.ubuntu.com/music/store/amz/ [Info 13:07:11.506] nereid Client Started [Info 13:07:11.674] GStreamer version 0.10.35.0, gapless: True, replaygain: False ** (Banshee:2692): DEBUG: Loading the real store page (Banshee:2692): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed Marshaling url-loaded signal Exception in Gtk# callback delegate Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
