Fatal error: Cannot create references to/from string offsets nor overloaded objects in ocupload.inc on line 583

Apparently the signature field stores its value differently to regular fields, this might be due to it not being translatable. Fixed it by adding a simple isset check - see attached patch.

Newest dev still has the issue and this patch still applies. I know it is not that common of a scenario to upload files into a signature field, but could someone just test this scenario and verfiry the bug / apply patch to change this issue to RTBC? White screen of death is not acceptable, hence changing to major.

I already found out mate, the signature field is no standard drupal text field and stored its value differently in $form_state['values']. Why would you assume this patch hides anything? Ocupload wokrs perfectly with the signature field after applying the patch.

Not sure what you mean, prime cause seems to me core signature functionality which by design stores its value differently. Please correct me if I'm mistaken.

• Enable signatures in user settings
• give users permission to use ckeditor and ocupload
• upload something into signature field on user account edit page with ocupload
• save user entity by clicking save.
• => WSOD with that error.

Error happens in _ocupload_field_value_by_html_name() which is called in ocupload_change_files_status() which is a submission handler called when submitting user account form.
