After updating to mozilla-firefox-1.0.7, mozilla-1.7.12 and gecko-sdk-1.7.12 liferea segfaults with the following error: (Gecko:13523): Pango-CRITICAL **: pango_font_map_load_fontset: assertion `fontmap != NULL' failed Segmentation fault Rebuilding with -firefox or -mozilla USE flags set separately doesn't fix this. Rebuilding with both -firefox and -mozilla set (and gtkhtml set) does work. Reproducible: Always Steps to Reproduce: 1. Build liferea with either firefox or mozilla USE flags 2. Run liferea 3. Actual Results: Application segfaults with above error. Expected Results: Application should start up and run.

I have no issue here with mozilla-firefox-1.0.7-r2. Did you tried this new revision? It has different patches for pango, i guess it could help.
Firfox-1.0.7-r2 and/or mozilla-1.7.12-r2 took care of the problem for me.
