There happens when I ZOOMING a POSTGRES vector layer with a line and arrow decoration (symbolproperties.png) causing the CRASH, I followed it with QT creator (qgis_test_00.png) to discover the problem, but I can't... It happens only on LINUX
I attach the sql to restore a table with an example of the problem. Thanks

Hi, since you are on Linux (what distribution?) please launch QGIS from the terminal and then post here the error message when it crashes. Post also as a log/text file the QT creator messages instead of a screenshot.

Hi, Giovanni the distribution is GNU/Linux Debian Squeeze 2.6.32-5-amd64. This is the complete error message from the terminal:

devgis@laptopdell:~/apps/bin$ qgis

The Qgis crash and just disappears, is the same message I put in previous post (qgis_test_00.png ) ;)
The log/text from QT is attached.

Gracias por la atención.
Obrigado.
