That code's been rewritten in 2.3.13 to read the quota directory  
instead.  You might be able to back port the change:

	https://bugzilla.andrew.cmu.edu/cgi-bin/cvsweb.cgi/src/cyrus/lib/ 
cyrusdb_quotalegacy.c.diff?r1=1.18;r2=1.19

For the record, it wasn't rewritten because of the bug you  
identified, but for an unrelated problem.
