Accerciser is a debugging tool for accessibility (think of it as an
accessibility inspector)
The version of accerciser currently in stable is actually basically
unusable due to bugs #848119 and #875629. The first prevents the python
console from working, thus preventing from hardcode debugging. The
second prevents from actually selecting a widget to inspect when not
using a desktop compositor, thus preventing basically everything. The
fixes have been tested for a long time in "testing", and are forwarded
upstream.
