 And both db1 and db2 have not spelling/synonym table:

 xapian-check db1
 spelling:
 Lazily created, and not yet used.

 synonym:
 Lazily created, and not yet used.

Comment(by olly):

 This means you are picking up the shared library (libxapian.so on Linux)
 from an older 1.0.x release.  That symbol is an "internal to Xapian"
 method which was added in 1.0.18, and is used by xapian-compact.  So
 you're running xapian-compact from 1.0.18 with libxapian.so from 1.0.17 or
 earlier.

 Try:

 {{{
 #!sh
 which xapian-compact
 ldd $(which xapian-compact)
 }}}

 If that doesn't make things clearer feel free to paste or attach the
 output from those two commands here (if pasting, put 3 { on a line before
 and 3 } on a line after so trac shows it nicely).
