I've just upgraded to Dharma from the PPA, and it's working great with one problem... when I try to scan a new artist to my music library, xbmc crashes.

The last message in the debug log is

DEBUG: ADDON: cpluff: 'Could not return information about unknown plug-in metadata.last.fm.'.

Looking in my addons folder, I see metadata.artists.last.fm, and metadata.albums.last.fm, but no metadata.last.fm.

My default scanner is set to AllMusic. I've removed and re-added the source and tried to scan it to my library, but have the same problem.

Help?

Sounds like you have out of date data in your database, likely due to you setting content or scanning during a period where addons was in flux.

Either way it shouldn't crash - mind posting a crashlog?

r33411 fixes a few potential NULL dereferences. Will be merged to Dharma in time for beta2.

Hrm. Looks like I don't have a crashlog present, for some reason. (I'm running the xbmc start script inside a standalone X session -- not sure what the problem there is, but I can fire it up by hand when I get home from work to see what happens)

Regardless, I just ran a backtrace on my last core file, and it looks like the xbmc binary I have installed has been stripped -- no debugging symbols.

I can provide a full backtrace, regardless, if it would be useful to you. bt of the parent thread gives this:

Looks like it might be totally unrelated to the last debug message?

[jmarshall]

Yeah - that's a generic backtrace of X tearing stuff down by the looks.
