Having problemas with surface creation

First of All let me say I find Avogadro an excellent program. I’ve been
using it lately and it’s been of great help to create Gaussian09 input
files and after displaying Gaussian09 results. Not many molecular modeling
programs available for Linux platform, and Avogadro is one of the best
I’ve ever used.

Didn’t have problems with Gaussian09 .fchk files, until reacently when I
tried to create density and ESP surfaces and Avogadro just cancels
execution.

Running it from a shell I get error output which I include below.

Hope someone can tell me what can be the problem. With some .fchk files I
have no problems, with others, I get this error:

QStackedLayout::setCurrentWidget: Widget 0x9524f58 not contained in stack
libpng warning: Ignoring attempt to set cHRM RGB triangle with zero area
