Error "No stream named styles.xml found." when reading ODS file
Error message when opening an ODS-file:
No stream named styles.xml found.
The ods file was created by a data export tool and only contained the following files:
An OpenDocument package is not required to contain a styles.xml file:
OpenDocument Version 1.2 Part 1: OpenDocument Schema section 2.2.1 A.2) "contain at least **one** of the following files : content.xml and styles.xml"
The current code already supports reading without styles.xml [plugins/openoffice/openoffice-read.c:13904] except for the check at [plugins/openoffice/openoffice-read.c:13741].
See attached patch gnumeric-ods-no-style_xml.patch for a fix.
