The newly implemented Balloon analyzer does not work from the web interface

+ I recently implemented the adapter for the 'balloon' analyzer. So, my first
thought is that something might be wrong there, though I couldn't find what.

+ Attached files:

> the file --h5 downloaded from TVB 1.1 for Mac 64 – with the simulated
time series used as input and that make the analyzer fail (error message
comes from abcadapter and says that NaN values were produced.)

> a small script that uploads the .h5 and uses the balloon analyzer. No
errors are thrown (no runtime errors, overflows error or floating point
related errors).

> the whole project, just in case
(https://dl.dropboxusercontent.com/u/15884660/2013-11-12_22-41_ModelingTheEffectsOfLesions_paupau.zip) . I'm using the 66 ROI's connectivity
matrix. It can also be found under: simulator/files/connectivity/hagmann_hemisphere_both_subcortical_false_66

svn revisions: 5251 & 5252 are the latest versions of both the analyzer and adapter.
