The respective new classes are RBA::Technology and
RBA::TechnologyComponent. This interface will replace
the current way of doing tech management from scripts
by using the "technology-data" configuration parameter.
This crash started to happen with the bugfix
for the black-on-black tree expander icon.
It was caused by the styling that was attached
to the widgets in order to fix this. Apparently
Qt does not like to attach proxy styles dyna-
mically.
Now, the styling is applied globally and this
issue is fixed.
