#3306 closed defect (fixed)

Query vector maps gives error

When using the wxGUI vector attribute query tool to get the values for a vector layer, I am getting an error (but only for polygons, querying points and lines seem to work?). For example, trying to query the geology layer in the NC dataset:

Failed to query vector map(s) <geology@PERMANENT>. Check database settings and topology.

Reason: "198808.723525"}}]}]}]}

Not sure if this has anything to do with ticket #3133? Using trunk r70721
