qgis crashes when viewing PostGIS tables

[cavallini@…]

When opening a PostGIS table, in various situations we get:

Warning: QPainter::begin(): Painter is already active.

You must end() the painter before a second begin()

Segmentation fault

This happens eg if we click on the table icon after inserting a point and committing changes, or when we allow editing, select a point, and click on the "cut" icon.

In one occasion, we also got:

Warning: X Error: BadWindow (invalid Window parameter) 3

Major opcode: 20 (X_GetProperty) Resource id: 0x1603586

before segfaulting.

After recent commit by mhugent (#5507) things have improved, but not solved; the crash does not occur in the first case (click on the table icon after inserting a point and committing changes), but it does in the second case (allow editing, select a point, and click on the "cut" icon).

I am not able to reproduce the second crash with my database. Do you have a debug version and a backtrace? Or what is the console output (besides the QPainter warning, which can be ignored)?
