Bug in delimited text plugin

[qgib]

Author Name: Chris Crook (@ccrook)
Original Redmine Issue: 3188

Redmine category:c++_plugins
Assignee: Jürgen Fischer

---

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

Steps to repeat.

1. Open QGIS in a new project
2. 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
2. Map should display 3 points
3. 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
