MythMusic abort() when changing visualisers

[anonymous]

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:

MythTV Version   : 19715
MythTV Branch    : branches/release-0-21-fixes
Library API      : 0.21.20080304-1

Mythmusic is being re-written and no-one* is interested in maintaining the existing visualiser code.

*Visualiser bugs have been open for years in some cases with no patches submitted.
