Comment 11 for bug 944077

Workaround in Inkscape 0.48.3.1 for affected files to avoid a crash when running an extension:
rename the id of <namedview> to "base".

Steps:
1) open affected file
2) open 'Edit > XML Editor…'
3) select the node <sodipodi:namedview …> in the list on the left
4) select the attribute 'id' in the upper right list
5) at the bottom right, the string of the id is shown in the edit field
   (probably something like "namedview12345" - numbers will vary)
6) overwrite the id string with "base", click on 'Set', close XML Editor
7) try again to run the extension
-> it should know work without triggering the crash.
