Invalid argument supplied for foreach() when saving no changes on Manage Images tab

So I thought I got my upgrade done (2.x to 3.x) and plupload integrated, but not so much ;)

On upload save (without plupload on, as it gives me no error messages) I get: Fatal error: Call to undefined function _pathauto_include() in /var/www/sites/all/modules/filefield_paths/filefield_paths.module on line 737

I solved this by upgrading to the latest dev version of filefield_paths module instead of using the 1.4 stable. Should perhaps mention that in the readme's or whatnot.

Now I get warning errors on uploads, but everything works fine(ish?)

Warning: urldecode() expects parameter 1 to be string, array given in path_set_alias() (line 90 of /var/www/modules/path/path.module).

One error per file uploaded. Saw a few similar errors in my searches here, but not this specific one, so thought I'd post it here. I tried removing my filefield alias for gallery_images, but that didn't help.

Anyways very cool that I (king noob) got this working tonight! Just ignore all the red and plow through. Now I don't have to click 50+ times to add a gallery.. novel really ;)

Also, side issue: If I click "save" on the empty manage images page, I get: Warning: Invalid argument supplied for foreach() in node_gallery_manage_images_submit() (line 244 of /var/www/sites/all/modules/node_gallery/node_gallery.pages.inc).

Maybe that could fail more gracefully if someone deems it important.
