Subject: [PATCH] patch: no-file-selected
Squashed commit of the following:
commit f887550276e324151947960292a7266c71aeb573

fix changing working directory (#621778)
The patch checks the value returned by xsane_back_gtk_get_filename. In
most places it will check the result properly (taking 0 for success),
except one case where it takes 0 for an error, and this happens in
xsane_browse_filename_callback (xsane-front-gtk.c). The new code would
abort copying the filename into preferences structure if 0 was returned,
and that's the OK case. I'm very curious how wonderfully it would blow
up if an actual error was returned, but that's a different story.
