Bug#388447: epiphany-browser: Printing causes crash (bug-buddy)

[Roberto Piscitello]

Severity: important

I use Etch, and I can confirm that, also for me, printing doesn't work
at all in Epiphany (2.14.3-2).
I noticed that the problem is also present while printing to a PostScript file.
Actually, the file gets correctly generated in a temporary location
(/tmp/epiphany-$USER-??????/print??????.ps). You can also open it with
Evince and it works.
So the crash seems to happen after the creation of the .ps file, but
before its move to its final destination (i.e. ~/output.ps).

I run epiphany under gdb, opened some sites in tabs and tried to print
one to ~/output.ps.
I got this output:

I then issued a "thread apply all bt" to gdb and got:
