Segfault when adding album to Various Artists and restarting

What steps will reproduce the problem? 1. Sort the library by Artist/Album - Year

2. Right click on the album -> Show in various artists
3. Turn off Clementine. Turn it back on. What is the expected output? What do you see instead? Clementine should start as normal and the album should still show in various artists. Instead, it segfaults. What version of the product are you using? On what operating system? Version 1.1.1-214-g29c61f1 Linux ShanaX61s 3.7.0-rc4 #1 SMP Mon Nov 5 18:34:41 GMT 2012 i686 Intel(R) Core(TM)2 Duo CPU L7700 @ 1.80GHz GenuineIntel GNU/Linux Please provide any additional information below. I was trying to replicate an issue where someone on IRC was adding the album to various artists but the setting didn't stick between Clementine restarts. In my case, it makes the player segfault. Running it in gdb sometimes circumvents the segfault (Look, it's everyone's favourite Heisenbug! Are you excited yet?) which allows me use `Don't show album in various artists' which makes the segfault go away. I did manage to luck out and get it to segfault in gdb. Before I post the backtrace, I should mention that I don't believe that I have the album locally (that is, Clementine would be unable to read the songs, write to them etc. etc.).

Here's the backtrace: Program received signal SIGSEGV, Segmentation fault. 0x08294594 in Playlist::GetTotalLength (this=0xaa841fc8) at /home/shana/Programming/clementine-player/src/playlist/playlist.cpp:1833 1833 quint64 length = item->Metadata().length_nanosec(); (gdb) bt

I should add that I DO have some albums that are in Various Artists, but those are there by default as I have never manually added any.

Sounds like you want to fix this one too :)
