Are you able to reproduce this problem again ?

Somehow I reproduced (twice shortly in row) this with Impress:

libreoffice-4.3.6.2-8.fc21.x86_64

IIRC it involved fast changes of focus between text field (edit mode)
and the slide as such (non-edit, items-move mode) and perhaps pressing
Esc key1.

It occurred when I was reintroducing myself to LibreOffice.
Now I am a bit calmer and/or not reproducing the issue with
libreoffice-4.3.6.2-9.fc21.x86_64.  At least yet, will report back
if the issue is reproduced.

Per non-sensible aObjName at frame #1, I guess we are observing some kind
of undo-stack corruption (elevating into frame corruption per frame #0).

Note that it might also be related to copy + paste of the whole slide.
Even now, with libreoffice-4.3.6.2-9.fc21.x86_64, it can do strange
things -- just now, I am unable to Undo such an action even though
I can see "Undo: Insert slides" active in the menu.
