All vector geometry deleted after editing with v.edit

Description
I really hope there is a simple explanation for this one...otherwise this is a serious bug. I was running v.edit from the terminal on a polygon vector in 6.5svn. I was trying to break two specific boundaries in order to merge them in another v.edit run. Here is the output from 'v.edit tool=break' (ids were obtained from interactive querying):
v.edit map=Bonavista_Waterbodies_clipped type=line,boundary tool=break ids=2599,2618 --v Selecting features... 2 of 3568 features selected from vector map <Bonavista_Waterbodies_clipped@PERMANENT> 100% Intersections: 0 Intersections: 0 0 lines broken Building topology for vector map <Bonavista_Waterbodies_clipped>... Registering primitives... 3568 primitives registered 88380 vertices registered Building areas... 100% 2475 areas built 2440 isles built Attaching islands... 100% Attaching centroids... 100% Topology was built Number of nodes: 3533 Number of primitives: 3568 Number of points: 0 Number of lines: 0 Number of boundaries: 2626 Number of centroids: 942 Number of areas: 2475 Number of isles: 2440 Number of areas without centroid: 1533 v.edit complete.
Next, I ran v.edit tool=merge, trying to merge two side-by-side boundaries that virtually overlap one another:
v.edit map=Bonavista_Waterbodies_clipped type=line,boundary tool=merge ids=2599,2618 --v Selecting features... 2 of 3568 features selected from vector map <Bonavista_Waterbodies_clipped@PERMANENT> 100% 2 lines merged Building topology for vector map <Bonavista_Waterbodies_clipped>... Registering primitives... 0 primitives registered 0 vertices registered Building areas... 0 areas built 0 isles built Attaching islands... Attaching centroids... Topology was built Number of nodes: 0 Number of primitives: 0 Number of points: 0 Number of lines: 0 Number of boundaries: 0 Number of centroids: 0 Number of areas: 0 Number of isles: 0 v.edit complete.
All vector geometry has been deleted! I have zoomed to full extent, I have exited Grass and tried re-displaying the vector, nothing. v.info confirms there is nothing in this vector:
v.info -t Bonavista_Waterbodies_clipped nodes=0 points=0 lines=0 boundaries=0 centroids=0 areas=0 islands=0 faces=0 kernels=0 primitives=0 map3d=0

No, I can't. I tried editing a few vectors in the NC location and things seem ok, although I only had time to try for about 15 minutes.
Fortunately, all is not lost; I can return to an intermediate vector dataset and resume my edits, but it is still frustrating. I'll try and takes notes on what happens the next time around.

In this case can you send me sample location and exact commands?

Downgrading priority.

Closed, please re-open if needed.
Please can you reproduce this behaviour in NC dataset?
