[Gambas-user] Segmentation fault (core dumped)

Sun Feb 28 04:08:50 CET 2010

Don't think so,  but i do have one default printer setup, it works fine
though?

I deleted my default printer and gambas now works fine!  This is very weird? 
I am guessing I need to report this to my distro, what do you think?

As always, many thanks!
