This was a genuine bug, and a nasty one.  It would occur when removing
items from a profile such that only one element is left.  0.8 is the
first affected version.

Commit bea2683 fixes that, but I think I will change the gexp code to be
less permissive, since this is really the root cause behind this.

Thanks for the report!
