Comment 4 for bug 487653

Thank you for reporting back and confirming that the issue (unfortunately) happens with yet another third-party clipboard tool.

The ChangeLog for 1.1.3 says the only change since 1.1.2 was a fix for the issue with firefox reported as #5738 <bugzilla.xfce.org/show_bug.cgi?id=5738>. Maybe this could serve as a hint because somehow Inkscape must receive a change in clipboard content - as a seemingly arbitrary output-extension is triggered by the mime-type of the clipboard content.
