So I'm working on this code: GPrinter.cpp
<https://github.com/memecode/Lgi/blob/master/src/linux/Lgi/GPrinter.cpp?ts=4>
(and it's header
<https://github.com/memecode/Lgi/blob/master/include/common/GPrinter.h?ts=4>
).
And GPrinter::Print when I call gtk_print_operation_run I get a printer
selection dialog (on Ubuntu Linux), where I select a valid printer and
click OK. At which point I'm expecting it to call the begin-print signal so
I can calculate the number of pages. But instead nothing happens... at
all.. it just kinds waits forever.
If I break the app at that point I get this stack trace:

...snipped unimportant stack frames...
Is there something I'm missing here?
Why is the GtkPrintBegin signal not called?

Matt
