Spotify for Linux is available as a preview at the moment however a few users including my good self are having problems with it.
I reported my issues in the support forum (along the a few others who are having similar difficulties), the response
"For those of you who still have problems with the 0.4.6.73 release and are familiar with GDB, can you perform the following two gdb-commands to help me pin down this issue:
1) "bt"
2) x/i $pc
and post the output?
Thanks"
Now can you ever imagine a developer on a support forum for windows software asking a mere user to run a debugger?

For the curious...
