When copying object (text, rectangle), the following additional data are displayed (Copy works properly.).

And if uniconvertor is installed, Inkscape freezes after a period of time (please see attached gdb log)

Version:
Inkscape version: 0.47 r22583 (build from tarball on SF)
Python 2.6.4
uniconvertor 1.1.4

Build and platform:
Build 2009-11-24 on Arch Linux (x86_64)

When this happens, do you have a java-based download manager running in the background that monitors the clipboard (e.g. FreeRapid or jDownloader) or a clipboard manager?

Could be a duplicate of bug #418242 “Incorrect call to output plugins (with persistent error message) on copy”:
<https://bugs.launchpad.net/inkscape/+bug/418242>

[Masato HASHIMOTO (hashimo)]

Thanks!! I confirmed that this issue occurs with xfce4-clipman-plugin 1.1.3 (clipboard manager).
As for xfce4-clipman-plugin 1.1.1, there is no problem.
I don't use java-based applications.
I think so, this is duplicate of it.

[su_v (suv-lp)]

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.

Linking as duplicate to bug #418242. Please add a comment and revert the duplicate status if you have new information that these issues are independent and should not be linked as duplicates.
