Package: libffado2
Version: 2.0.1+svn1856-5
Severity: serious
While trying to write a ffado output plugin, MPD crashed with the
following double free bug (backtrace shows it's inside libraw1394, but
my guess is that libffado calls libraw1394 with an invalid pointer):
ERROR: messagebuffer not initialized: 1250648744531: Error
(IsoHandlerManager.cpp)[1289] ~IsoHandler: BUG: Handler still running!
