6140	MythMusic abort() when changing visualisers	anonymous	Isaac Richards	"Hi.

MythMusic crashes randomly when Synaesthesia visualiser terminates (mostly when a song ends; I have random visualisations selected).

Back-trace included. Please let me know if you need the actual core-file.

This only occurs on my multi-core (AMD Phenom(tm) 9850 Quad-Core Processor) based system:
