I've mentioned this a few times, but with random frequency, Amarok will either freeze or disappear under Apple's X11 on OSX.  Sometimes it is several times in a row, and often it is several weeks between occurrences.  Since upgrading to 1.4.6, it seems to be more often, so I have been running amarokapp from the command line in hopes of catching it.  What follows is a "normal" song-change event, followed by a "crash" song-change event.  For the record, I am running:

Version: Amarok 1.4.6 (source build via fink.  Same issue occurred with earlier versions)

OS: Mac OSX 1.4.10

DB: Internal SQLite

System: Mac Pro 2.6Ghz, 3GB, Amarok library is on secondary local disk (same issue occurred with a networked library, I moved the files local to eliminate "network issues" as a cause).

Engine: Xine

Normal Song-Change event:

Again, this usually happens within a second of song-change.  Sometimes Amarok appears to hang, sometimes it disappears entirely (like this event).  Any ideas are welcome, and "Wait until a native build in October" is a VALID response.  I am hoping for Amarok to blow iTunes out of the water once and for all once it is native, and I'm hoping to squash any showstoppers early.

I'm also suspicious of Apples X11, since everything seems somewhat less stable, both QT and GTK apps crashing under excessive use of the scroll-wheel for instance.  Maybe I just have two messed up Macs, but I hope not.

Thanks!

Here's what it looks like when Amarok freezes:

Amarok is crashing...

It's looking for /Users/xrayspx/News/Pan/1 just because I was in that directory when I launched Amarok. 

Sorry, I'd check but at the moment I can't get Amarok compiled on OSX. I suspect I need to get a more recent Dev Tools package.
Perhaps try disabling moodbar in settings?

Yeah, the moodbar isn't there, and I didn't install the plugin.  It's greyed out in the menu.  I don't get why it's doing that honestly.

I tried the KDE4/Amarok 2 native install, but it wouldn't scan the collection, and personally, I really didn't like the UI changes wrt artist list & playlist, with the context stuff down the middle.  I'm sure that as that becomes more stable, there will also be UI changes along the way

My money is still on X11 and maybe timing.  In any case, thanks for the input.
