Assertion failure when path of items in playlist is not available

[arnova]

I play my files from an smb share and when it's not mounted (yet) and I try to play something from the playlist I get an assertion error:
`
ASSERT INFO:
/usr/include/wx-3.0/wx/dynarray.h(838): assert "uiIndex < m_nCount" failed in Item().

BACKTRACE:
[1] Guayadeque::guPlayList::AddToPlayList(Guayadeque::guTrackArray const&, bool, int)
[2] Guayadeque::guPlayerPanel::AddToPlayList(Guayadeque::guTrackArray const&, bool, int)

Ideally Guayadeque would simply show an error dialog after which one can retry (when the path is mounted/available).
