            Bug ID: 143771
           Summary: FILTER: FILESAVE: When xml export xsl transform file
                    not found, error message is vague and misleading:
                    "Error saving document" "General input/output error"
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: minor
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: gekacheka at yahoo.com

Description:
When an xsl transform file for a custom export xml filter is not found,
and an export using the filter is performed, the error dialog message is 

  Error saving document (document filename):
  General Error
  General input/output error.

A much clearer error would specify the filter name, not document name, and
specify that the transform path, not the document path, is the problem:

  Error loading XML Filter "(filtername)":
  File not found at: (xslt file path)





Steps to Reproduce:
Steps to reproduce:

1. Create an xsl file (such as \exportbug\copy.xsl that copies its input):

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
</xsl:transform>

2. Add the custom xml filter to Calc
2.1 Tools (menu) / XML Filter Settings ...
2.2 General (tab)
2.2.1 Filter Name: Copy input xml
2.2.2 Application: LibreOffice Calc (.ods)
2.2.3 Name of file type: Copied Xml
2.2.4 File extension: xml
2.3 Transformation (tab)
2.3.1 XSLT for export: \exportbug\copy.xsl

3. Export file
3.1 File (menu) / Export ...
3.2 Export dialog
3.2.1 Save as type: Copied Xml (.xml)
3.2.2 click Save 
["Untitled 1.xml" file is saved, no error occurs.]

4. Outside LibreOffice, move or rename folder containing copy.xsl (for example,
rename exportbug to exportbug1)

5. Repeat step 3.
[Error occurs.]


Actual Results:
Actual Error is vague and misleading:

  Error saving document Untitled 1:
  General Error
  General input/output error.


Expected Results:
Expected error specifies that the problem is loading the xslt file, not saving
the document, and specifies the path not found.

  Error loading XML Filter "Copy input xml":
  File not found at: \exportbug\copy.xsl


Reproducible: Always


User Profile Reset: No
