Hi!

First of all, simon is not an official KDE project, so technically the correct place for bug reports is our bug tracker at sourceforge: http://sourceforge.net/tracker/?atid=935103&group_id=190872&func=browse

Could you please paste your simonrecognitionrc (in ~/.kde/share/config/simonrecognitionrc)?

I think I found the bug (insufficient input checking in the recognition control) but it shouldn't be triggered as long as your input is correct.

Your config file should have a line similar to this (if you use the default values):
JuliusdServers=127.0.0.1:4444

Regards,
Peter
Comment 2 Samuel Brack 2011-01-05 14:32:55 UTC
Marked as downstream, please report the bug to the tracker mentioned in comment 2. KDE bugzilla is unfortunately the wrong place for this report.
