When you restart Rosegarden, it though has remembered your added symbol and it works then, you can click on it and it works correctly as intended.

hmm it doesn't seem to crash with 1.7.0 here, could you please try with either 1.6.1-r1 or 1.7.0 ? Perhaps we just need a new stable, Diego, opinions ?

Albert and what about 1.7.3? If it still fails, could you open bug report at upstream bugzilla http://sourceforge.net/projects/rosegarden/support and post link here? Thank you for detailed bug report, btw.
Well, I've tried to reproduce this problem in 1.7.3 and it looks like it works here... But please, check yourself.
No update and works for me.
