There is a segfault in this most recent beta version of Spotify when running on fully up to date Archlinux, in where if you quickly resume a song right as you are opening spotify, you will get a segfault. The error reads:
../../third_party/tcmalloc/chromium/src/free_list.h:118] Memory corruption detected.
/usr/bin/spotify: line 2: 3139 Segmentation fault (core dumped) LD_PRELOAD=libcurl.so.3 /usr/share/spotify/spotify $@
It usually happens when I was listening to a spotify playlist under Genres & Moods. It's hard for me to track down exactly where this issue pops up, but you can usually invoke it when you press spacebar right as the program is opening to resume the song you were playing.
