I maintain a library that reads and writes Microsoft Excel files. Due to some recent changes neither Preview, Quicklook or Numbers can open the file. Is there are any way to get debug information from any of these (or the underlying libraries)?
I'm specifically looking for command like flags such as -d 4 which will provide more information as to why the Preview / Quicklook / Numbers can't open the file. ie. some kind of informative error message such as "can't parse the XML".
Feedback from the OOXML Working Group about relative references:
What do you mean by a relative reference? In RFC 3986, a relative reference is either an absolute-path reference (e.g., /foo/bar) or a relative-path reference (e.g., foo/bar). OPC already allows both.
So this is a bug in the Apple software stack. I'll update the bug report accordingly.
