ubiquity crashed with InstallStepError in configure_ma()

[Gamal+]

Binary package hint: ubiquity

configure_ma()
This is the attached function .. almost before finishing the copy process :@

My Machine:
AMD64 and I'm installing a normal 32Bit version.

My Session:
Live session

My Guess:
I installed a package while the installation and uploads Icons appeared up there after the installation of the package ..
and it made the installation windows disappear, but after issuing the "top" command and changing my appearance to normal it appeared again.

Then I was using flash in youtube video in which I guess it was overloaded or something .. I don't know ..
I'll attach the log file(s).

Kindest regards, hope that help,
