Comment 11 for bug 748842

Doesn't look like the same issue to me since the stacktrace is completely different. Regardless, it seems to be some sort of library issue and not caused by linuxdcpp. There have been various library issues before with people running linuxdcpp using theme engines on non-GTK+ based desktop environments. This issue originates when loading the glade xml via libglade, so moving to GtkBuilder will as a side effect fix this issue, but I'm not sure that libglade is the actual cause.
