db unavailable in regular filters

[patlx]

db property is available in Supertool window:

but if you save the same code as a regular Gramps filter this error occurs:

Oh yes, the filter feature seems to be quite incomplete. Most other "global variables" are missing too. Will be fixed. Thank you!

This was fixed in Supertool 1.2.9.
