Description Damon Lynch 2015-01-21 11:40:56 UTC 
Mistakenly calling get_volumes() directly on a VolumeMonitor causes a core dump:

$ python3
Python 3.4.2 (default, Oct  8 2014, 13:08:17) 
[GCC 4.9.1] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import Gio
>>> v = Gio.VolumeMonitor()
>>> v.get_volumes()
Segmentation fault (core dumped)

The correct way to call get_volumes() is to do this:
>>> v = Gio.VolumeMonitor().get()
>>> v.get_volumes()

The simple error of not including the .get() probably should not cause a core dump.

This also segfaults when using the C API:

#include <gio/gio.h>

int main(int argc, char *argv[]) {  
  GVolumeMonitor *monitor = g_object_new(G_TYPE_VOLUME_MONITOR, NULL);
  g_volume_monitor_get_mounts (monitor);
  return 0;
}
