Removing the 'child-VOBs' that are automatically added by adding a first VOB causes an instant crash
Win 7 x64, MKVtoolnix GUI v.29.0.0
If I have some VOBs from a DVD named like: VTS_03_1, VTS_03_2, VTS_03_3, VTS_03_4
Adding the first one by itself adds 03_2, 03_3, 03_4 automatically, which is fine, but because of another bug (which I will make a separate report for) which doesn't seem to apply the specified framerate across all the parts properly when they're merged to a single MKV, I tried to make each part a separate MKV which I then planned to merge.
To my surprise, right-clicking a 'child-VOB' WHICH ISN'T the last child(!), and choosing 'Remove File' causes an instant crash.
