Bug#874051: swami 2.0.0-svn389-5 seg faults with error 4 in libgobject-2.0.so.0.5304.0
Package: swami Version: 2.0.0+svn389-5 Followup-For: Bug #874051 Dear Maintainer, The segfault seems to be related to the fluidsynth_plugin.so plugin. If I rename this plugin the crash no longer happens (there are other warnings then). Here is a stacktrace from gdb when the segfault happens. Sorry, I don't have swami debug symbols.
