Description
I just clipped a layer of contiguous polygons using qgis's inbuilt 'clip' function.
The result opens fine, but causes a crash when you try to open the attribute table.
The attribute table opens fine for other shapefiles, so guess it's clip's fault.
Would be interested if this problem is replicated in other versions (see attached).

p.s. I'm using the latest master branch qgis 1.9.0+git20130330+0229ea9~precise-ubuntugis1

- Status changed from Open to In Progress
Was caused by the second last column which seems to have no name (empty string)
The following patch makes this more stable:
https://github.com/qgis/Quantum-GIS/pull/495
Still, the problem persists, that QgsExpression is unable to handle an empty attribute name.

Many thanks to speedy update.
Could not verify that the fix works on latest qgis version on my system, however (supplied by the following repos:
#deb http://qgis.org/ubuntugis-nightly precise main
#deb-src http://qgis.org/ubuntugis-nightly precise main)
Opening the files caused a crash, but this may have because of problems with python-qgis, which occurred while upgrading the system (see terminal report below). Instead I've reverted to qgis 1.8.0-1~precise3, which opens the attributes fine.
