I'm also having this problem on Ubuntu 13.10, Inkscape 0.48, and Netbeans 7.3.1.
The easiest workaround I have found is using Diodon to clear the clipboard after copying anything in Inkscape and before clicking on another affected application like Netbeans. Just install Diodon sudo apt-get install diodon and it will add an icon to the panel (top right) where you can easily manage and clear your clipboard. Really all you have to do to avoid the endless popups is add anything other than an Inkscape object to the clipboard, so with Diodon you could select a recent clip. I have noticed though, that if you have the Diodon automatic paste enabled and you have an inkscape object selected when you select a clip from Diodon it may change the object's settings like color and opacity. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to inkscape in Ubuntu. https://bugs.launchpad.net/bugs/418242 Title: Incorrect call to output plugins (with persistent error message) on copy Status in Inkscape: A Vector Drawing Tool: Triaged Status in “inkscape” package in Ubuntu: Confirmed Status in “inkscape” package in Debian: Confirmed Status in Gentoo Linux: Unknown Bug description: UPDATE: After further investigation it turned out to be a problem related to the copy operation, in combination with a totally unrelated running Java program (FreeRapid). Reading some followups and other bug reports, it seems to be caused by the new clipboard management system (introduced as a fix for the bug #170185), as reported in bug #421597 So far these applications are known to randomly trigger an input/output extension (on linux): - FreeRapid Downloader - jDownloader - xfce4-clipman-plugin 1.1.3 - Netbeans - xfce4-settings-helper (Xfce 4.8) ----- The original report was this: I'm getting this error when I try to edit a text object created previously with a font that's not available in this system. It looks like Inkscape has problems to resolve the font substitution and displays the error message in a popup window that keeps appearing again and again, leaving no other remedy than closing inkscape and reopening it.
