Some parts of the plasma-workspace need the semantic-desktop use flag to be built (i.e. the krunner nepomuk search engine). Reproducible: Always Steps to Reproduce: 1. Compile kdebase-4.2.0 without semantic-desktop useflag disabled 2. recompile affected ebuilds with semantic-desktop useflag enabled 3. semantic desktop and indexing is working but you can't search because krunner search engine is missing (which is in ebuild plasma-workspace-4.2.0) Easy workaround is to recompile plasma-workspace-4.2.0 ebuild after changing the semantic-desktop useflag
Hmm, apparently you're right, I'll investigate
Foxed. Thanks for the report and sorry it took so long.
