Wow! Never seen this. Does it happen all the time, or was this a one off?

Thanks for the backtrace - it does help very much.

Another question, do some of your albums have music brainz ids? And is MPD 
configured to use these?

Still not recreated the crash, but I did see some errors in the code. These 
have now been fixed in trunk and branches/1.5 Can you update and confirm if 
these fix your issue?

Hi Craig,

Regarding your questions:
1. It happened multiple times, but only if I added music (not touching the 
collection + updating does NOT crash)
2. I usually don't maintain mbids, but some albums may have them
3. It seems that everything's fixed with r5639 :)

Thank you!

Great, thanks for confirming the fix. As to mbids, you would also need to have 
configured MPD to use these (in the metadata_to_use setting). Anyhow, don't 
really think this was the issue (but there was an error due to this change)...

I'm using the default settings for this:
#metadata_to_use        
"artist,album,title,track,name,genre,date,composer,performer,disc"

-> "The default is to use all known tag types except for comments."
So my mpd is probably using them.

Thanks again for digging into this so quick :)
