Comment 3 for bug 1179161

No more problems as of my testing tonight. However, I swear just a few days ago I had to close parcellite to make Inkscape be able to paste again. As of tonight, I'm unable to find out the combination of events that caused that to happen however. I'll post how to replicate it if I find out how to, but as of now, its working on:

Parcellite 1.1.5
Inkscape 0.48.4 r9939
Lubuntu 13.10 with a custom 3.11.0-13.20 Kernel. The only change being "HID_MAX_USAGES" is set to "64000'' in order for my mouse to work.

Intel 3570k, 16gb ram, hd4000 graphics

I'm not quite certain what you are referring to by complex objects, but I'd be happy to test if you are curious if its working now on the more current releases! Copy and pasting a graph in Libreoffice Draw resulted in no problems on LibreOffice versao 4.1.2.3
