Re: [Gimp-print-devel] New Printer Debugging Strategy Help

[Erik B. of T. <ba...@ta...>]

Thank you sir!

Good suggestions all, I will start using them and let you know how I
make out.

Regarding the core dump, yes the crash report did have one.  I'm rusty
at using gdb and other tools to look at core dumps, so I'll have to
spend some time boning back up on how to do this.

Regards,

Erik
