libgbf-1-2 overwrites /usr/bin/gbf-am-parse, which is also in Anjuta

[Sense Egbert Hofstede]

Binary package hint: libgbf-1-2

When you update from 8.10 to 9.04, you'll get an error message that Anjuta couldn't be installed because the package anjuta also contains the file /usr/bin/gbf-am-parse
When you remove Anjuta and libgbf-1-2 and try to reinstall it you'll get an inverse version of the error message since libgbf-1-2 is installed later.

I think this is because libgbf-1-2 is still 2.24.
