Description:
I accidentally saved my important spreadsheet as .UOS. It cannot be opened with libreoffice. When you open the file with libreoffice calc it fails:
runtime error: file file:///usr/lib/libreoffice/program/../share/xslt/import/uof/uof2odf_spreadsheet.xsl line 3262 element value-of
xsltApplySequenceConstructor: A potential infinite template recursion was detected.
You can adjust xsltMaxDepth (--maxdepth) in order to raise the maximum number of nested template calls and variables/params (currently set to 3000).

Steps to Reproduce:
1.Create spreadsheet with lots of data and charts
2.Save as .UOS "Unified Office Format"
3.Open file with libreoffice calc

Actual Results:
Popup with: General Error. General input/output error
Command line says:
runtime error: file file:///usr/lib/libreoffice/program/../share/xslt/import/uof/uof2odf_spreadsheet.xsl line 3262 element value-of
