[Jde] Problema con driver Firewire

[Gonzalo Abella]

Buenas,

estoy trabajando con las cámaras firewire y el driver me está dando
problemas en las máquinas nuevas, en concreto en "ordago". El jde carga
todo, pero cuando inicias "colorA" revienta. Usando "gdb" esta es la traza:

Cuando lo ejecutas normal te sale lo siguiente:
