Hi there, I did it again. The update-manager gdb session would not crash on me, so I tried ctrl+C and then the gdb session of the update-manager gdb session crashed and it did have stack. The update-manager gdb session itself did not. Also dpkg --configure -a gdb session gave the same (type off) output again. I hope this helps.
