I can't reproduce this here on 1.0.1.

Your title says fast-forward but your steps say fast-rewind. Do both cause the crash or only one? How many songs (and of what kind) need to be in the playlist to trigger the crash? Does it crash if you use one of the buttons at the bottom of the window to skip forward/back instead of a hotkey?

Can you try getting a backtrace? Type: gdb clementine run (make it crash) backtrace

Then paste the output here.

You forgot the important part which was typing "backtrace" at the end :)
