Comment 1 Matěj Cepl 2011-05-16 22:01:14 UTC 
b.g.o suggested that this is a duplicate of my other bug 647032.
Comment 2 Christophe Fergeau 2011-05-16 22:05:37 UTC 
The interesting bit of the backtrace is

+ Trace 227153

  • #0 g_str_hash
    at gstring.c line 142
  • #1 g_hash_table_lookup_node
    at ghash.c line 313
  • #2 g_hash_table_lookup
    at ghash.c line 902
  • #3 rb_refstring_new
    at rb-refstring.c line 88
  • #4 rhythmdb_entry_sync_mirrored
    at rhythmdb.c line 3669
  • #5 rhythmdb_entry_get_string
    at rhythmdb.c line 4757 

Looking at rhythmdb_entry_sync_mirrored, rb_refsting_new is called with the result of val = rb_utf_friendly_time (entry->last_seen); which returns NULL when entry->last_seen is 0, which is the case here, so this would explain the bug. Looking at the backtrace from bug #647032 this indeed looks like a duplicate, I was confused by the initial comments from hadess, didn't pay attention he said it was a different bug.
