Bug Description

This bug can be reproduced as follows:

1. Create a new guide.
2. Double-click the guide to open the guide dialog.
3. In the "Label" text-field, type the name you want to give the guide.

What will be observed is that "sodipodi:guide" becomes the name of the guide. It can also be observed that "sodipodi:guide" is the value of the attribute "inkscape:label".

Double-clicking the guide and then re-attempting to change the label of the guide will cause the label of the guide to be rendered, but the SVG will not have been updated.

Steps to reproduce vary (testing with r11573 on OS X 10.7.4) - corruption mostly occurs after repeated edits of a guide's label (inserting characters seems to trigger the error more often than adding characters at the end), sometimes may produce broken SVG file which Inkscape can no longer reopen:

Looks better with the patch from comment #3. Tested on Windows XP, Inkscape revision 11575, and you now can modify the label as long as you're working on a new file.

But after saving and reloading the file, label modification sometimes adds invalid characters, hides the guide (it exists in the XML file but is not rendered, while other guides are), triggers various rendering weirdnesses (when zooming/panning) and even freezes or crashes the application (when editing the name from the XML editor).

New report(s)?

Yes. I can confirm this.

Just generated a SVG that has guide labels in them.

Reopening the file rendered the guides correctly, but trying to change the guide causes the label to be rendered with unreadable characters. The XML, however, is updated.

The guide then isn't rendered anymore, i.e. it 'disappears'.
