Why SIGABRT

[JoÃl KrÃhemann <weedlight at gmail dot com>]

Hi, my name is JoÃl KrÃhemann and I'm developing Advanced Gtk+
Sequencer. I get the following backtrace out of gdb. `ags` should be
thread safe so perhaps it's more related to glib and the root cause
may be line 4 and: have_lock=0

I'll read the source code of glib for further investigation, assumed
someone knows the problem it would be nice to know it.

What about ignoring SIGABRT?
