Comment 1 Andrea Diamantini 2011-02-28 12:38:14 UTC

I'm working on preventing rekonq to crash in such situations. Anyway, I truly think this crash depends on a broken KDE installation in your system. It seems you are missing some runtime deps like the UA services.

Comment 2 Andrea Diamantini 2011-02-28 16:00:53 UTC

Git commit c9ab4595a61640c157f55c1d7908d8fc6bf2ec9e by Andrea Diamantini.
Committed on 28/02/2011 at 15:58.
Pushed by adjam into branch 'master'.

Prevents rekonq from crash if an UA service cannot be found.
This fix needs IMHO an extra informational string that will be postponed to after 0.7 stable
release.
