I think its not a bug. There must be always a clef. At least in the first system. Its a style option to omit clefs in following systems (used in lead sheets).
Deleting a clef replaces it with the default (treble) clef.
I agree there must always be a clef, but I think if you want to change a clef, you drag it from the palette. Deleting it seems an inaccurate response (it shouldn't do anything) - especially default clefs of an instrument.
Comments
It appears to affect all clefs, except the normal treble one.
You don't have to create a part either.
This only applies to clefs at the start of the score.

Maybe similar (please say if otherwise):
1. Open attached score.
2. Click on first bar.
3. 'Delete Selected Measures'.
Result: All bars are treble clefs.

it works the same for barline. It's by design.
