Seahorse crash

[Francesco Groccia <fgr@xxxxxxxx>]

Hi,
when I try to sign a file (command: 'seahorse-tool -s file.ext'),
Seahorse crashes with this message:

###
** (seahorse-tool:6760): CRITICAL **: prompt_signer: assertion
`GPG_IS_OK (gerr)' failed
###

That means I don't use seahorse nautilus integration.

Additional info:
Arch64
seahorse 2.26.2-1
gnome 2.26.3

What happened?
