Description

Accessing attributes in a delimited text file layer causes QGIS to crash.

Steps to repeat.

1. Open QGIS in a new project
 1. Select a project CRS with parameters:
+proj=merc +lon_0=0 +lat_ts=0 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m +no_defs


 1. Click the delimited text plugin and enter text file: attached file test.txt
  layer name: text
  delimiter string: \\t, plain characters
  X field: x   Y field: y
  click OK
 1. Map should display 3 points
 1. Right click layer in the layers list and select "Open attribute table"

QGIS dies with the Windows 'Send error report' dialog.

Operating system: MS Windows XP, service pack 3
QGIS version: 1.6.0 - build 14500
