Description
When we try to delete a point in postgis table qgis crash:
Warning: QPainter::begin: Painter already active Segmentation fault
This happens every time we allow editing, select a point, and click on the "cut" icon. It doesn't happen with linestring or polygon.
The problem is similar to http://svn.qgis.org/trac/ticket/132
I don't know if it's could be correlate, but connection to db seems lower than before.

The bug fixing caused a side effect: If I try to select from query builder on a table (I tried also as db superuser with full grants) I get an error message: 'Connection to database failed: FATAL: password authentication failed for user "username"'. Furthermore, if I select all records from a table with missing geoms, then zoom to selection, qgis crashes. If I exclude the records with missing geoms, the zoom works well (no crash). So missing geoms appear to be a problem not only for digitizing, but also for selecting. The query builder might be a side effect?
Works for me.
Can you provide a backtrace from the crash?
