Rosegarden thorn Segmentation fault in AlsaDriver.cpp:1308

Hi, I filed bug 2885468 a while back and it was requested that I contact
the list as well.
When loading the attached file "bug-549855_m100.rg" I get a segfault. A
copy of the gdb output and backtrace is attached. It still occurs in svn
11150. I've tried to debug it and if I step through
AlsaDriver::connectSomething I don't get it I have to run full speed to
1308        setPlausibleConnection(toConnect->getId(), ""); for it to
occur. Sorry my c and c++ skills are still in the making and I can't
offer anymore help.
Regards
Dave P
