qgis crashes when viewing PostGIS tables

Crashes QGIS or corrupts data: Copied to github as #:10191

Description

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.

History

#1 Updated by Redmine Admin over 18 years ago

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).

#2 Updated by Marco Hugentobler over 18 years ago

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)?
